In the automatic mode, the light reflected by the subject is detected by a photoresistor in the auto-thyristor module on the front of the 283. A small capacitor in series with the photoresistor charges through it. When the voltage across the capacitor reaches some predetermined amount, the flash discharge is quenched. 6 The abbreviation, s, stands for microsecond. The prefix, micro-, represents millionths. Thus, 1 s = 0.001 ms = 0.000001 s. 7 This results because the resistance of the photoresistor decreases as the light intensity increases. The lower the resistance, the quicker the series capacitor will charge. 8 This is the photoresistor referred to in footnote 5.
close to the wall and then again when it is as far away as you can get it. Use the yellow automatic mode. (You should have found that the yellow mode gives the shortest flash of light.) Did you get the brighter flash when the unit was closer or farther from the wall? Can you explain why this result is to be expected?
What does this tell you about where you should place the flash unit for taking high-speed photographs?
3. A third way to change how much light is reflected to the light detector is to change the background. A dark background will obviously reflect much less light than a white one at the same distance. Try this by discharging the flash unit first toward a white wall and then toward a black curtain at the same distance as the wall. What did you find out? 4. Of the second and third factors discussed above, the second is the more important. Thats because a black background can still reflect a significant amount of light. Its usually best to set the auto-thyristor module on yellow and place the background as far away as possible from the subject being photographed. In order to review what you have done so far, what three things can you do in order to obtain the shortest burst of light from the flash unit? a.
One would use darker filters in order to use smaller apertures for greater depth-of-field. For high-speed photography, however, the greater flash duration that results is usually undesirable.
In addition to minimizing flash duration, using the yellow automatic mode will maximize battery life. Therefore, whenever possible when using batteries, be sure the flash unit is placed in the yellow mode and that the flash head is in the 90 position so that the reflected light reaches the light detector. Be sure, of course, that your hand doesnt cover the detector. 5. The Vivitar 283 has a feature that makes it possible to conveniently adjust flash duration. Note that the auto-thyristor module can be removed. Pull it straight out, away from the flash unit. This will expose an arrangement of five holes. The two holes on the right (as seen with the flash unit upright and facing you) are the connections for the light detector. By inserting the leads of a variable resistor into these two holes, you can control the flash duration (and brightness) directly. Try this now with the 100-k variable resistor. Activity 3. Measuring flash duration Additional equipment: 100-k variable resistor AC motor with clock disc Ring stand and clamp Electronic stroboscope Background: The duration of the flash cant be read directly from a dial on the unit, but there are methods of measuring it. The method that will be used in this activity is to set up a motor as a high-frequency clock. A black cardboard disc is centered on the axle of the motor to serve as the clock face. A bright, radial line painted on the disc serves as the hand, as shown in the figure to the right. If the motor rotates fast enough, the hand produces a perceptible blur under the illumination of the electronic flash. 1. Clamp the motor10 onto a ring stand. Then turn the motor on. If youre using an openframe AC motor, dont let it run more than a few minutes at a time. It heats up quickly and will burn the insulation. Use the electronic stroboscope to measure the frequency of the

The motor used for the clock is the type used to operate cooling fans for appliances. The frequency is 50 - 60 rotations per second.
motor. This is done by adjusting the stroboscope frequency until the hand of the clock disc appears stationary. To insure that the clock hand is making only a single rotation between flashes, double the stroboscope frequency. If two equally-bright images of the hand are seen 180 apart, the original frequency was the correct one. Record the clock frequency in flashes per minute. Then calculate the number of flashes per second. Clock frequency (fpm) = Clock frequency (fps) =
2. Calculate how long it would take for the hand of the clock to move through an angle of 90. Repeat for 1.
3. In order to use the clock to make accurate measurements of flash duration, its necessary to take photographs of the rotating disc. For this activity, however, you can simply view the disc and make relative judgements about the angle through which the hand moves. Set the flash unit on the purple automatic mode and point it at the rotating disc, about a meter away. Discharge the unit, watching the disc as you do so. Back up to larger and larger distances from the disc, noting the amount of blur each time. Then repeat with the flash unit set on the yellow automatic mode. Also try with the auto-thyristor set on M. Finally, make some tests with the 100-k resistor replacing the auto-thyristor module. Give the results of the tests.

Activity 4. Triggering the flash unit with sound Additional equipment: Piezoelectric sound trigger Balloon and pin Background: Youve already seen how to trigger a flash discharge by shorting across the flash terminals. In this activity, you will use a sound trigger, a circuit that shorts the terminals electronically in response to sound. The three parts of a sound trigger are a microphone, an amplifier, and a silicon-controlled rectifier (SCR). The diagram to the right shows how the components are connected. The microphone picks up the sound of the event to be observed. The amplifier boosts the current from the microphone signal in order to actuate the SCR, The SCR acts as a switch to short the flash terminals, which are connected to the cathode (C) and anode (A) of the SCR. The amplifier output is connected to the gate (G) and cathode of the SCR. When a sound is picked up by the microphone, the amplified electrical current flows in the gatecathode circuit of the SCR. That in turn allows current to flow in the anode-cathode circuit, thus discharging the flash unit. Besides acting as a switch, the SCR isolates the amplifier from the voltage across the flash terminals. The sound trigger for this activity uses a piezoelectric film as the microphone. The film is pressure-sensitive, producing a voltage spike in response to the sudden deformation caused by a loud, sharp sound such as a hand clap or balloon burst. A diagram of the internal components of the trigger is shown on the next page.11 The 5-k potentiometer serves as a variable resistor to provide sensitivity control. A 9-V source is connected to pins 1 (+) and 3 (-), and the flash terminals to pins 2 (+) and 3.

Activity 6. Photographing the smash of a tennis ball or racquetball Additional equipment: Piezoelectric sound trigger Tennis ball or racquetball and racket Large cloth sheet or blanket The setup for this photograph is more involved than that of a balloon burst, but it can easily be done in a classroom. A typical arrangement is shown in the overhead on the next page. Place the sound trigger as close as possible to the place where the collision of the ball and racket occurs. If one were doing a forehand shot, for example, the sound trigger could be placed on a stool or box about a foot below the spot where the racket met the ball. Of course, sufficient room would have to be left around the person wielding the racket to allow freedom of movement. The background can be a problem if you plan to include the person swinging the racket in the photo. You may want to dispense with a hung background and simply make sure the subject is far from a wall and that distracting objects are removed from the background. The ball can easily be stopped without rebound in a sheet or blanket hung from the ceiling or held at the ends by two people. The position selected for the camera depends on whether one wants a side view, front view, or back view of the ball. The flash position should be selected so as to avoid throwing unwanted shadows across the ball. Set the sensitivity of the trigger as high as possible. A piezoelectric sound trigger may not work consistently for the thud produced in the collision of the racket and ball.13

For a much more sensitive trigger, try the tape recorder sound trigger described in Appendix E. Take note of the special precaution given in Activity 8.
Before attempting photographs, have the person who swings the racket take some practice swings with the room lights on. Then repeat with the lights off. If the room is too dark, a penlight can be used to illuminate the ball during the swing. The flash will probably be bright enough in comparison so that the light from the penlight is not noticeable. If you wish, try different camera, flash, and sound trigger positions in order to examine how the shape of the ball changes throughout a collision. Also, compare the deformation of a tennis ball to that of a racquetball, which is much softer than a tennis ball. Activity 7. Using a contact trigger to capture a football kick Additional equipment: 1-2 m long hookup wires Aluminum foil Football and tee Backstop blanket This activity uses a very simple trigger, a metallic switch, to photograph a football kick. Two wires are connected to the PC cord14 and are placed in front of the football so that they are not touching. When the football is kicked, the wires touch and the flash discharges. The arrangement of equipment is shown in the overhead view to the right. The football rests on a tee. A heavy blanket hanging from the ceiling serves as the backstop. The bottom of the blanket should not be secured tightly; otherwise, the ball will bounce from it. Secure it just enough to prevent the ball from slipping underneath.It will help if the blanket drags the floor. It's also a good idea to place a large foam pad below the blanket to keep the ball from bouncing off the floor.
The wires may be taped to the terminals of the PC cord using the method described in Appendix D.
The camera may rest on the floor or be raised with a stack of books. The flash is placed nearby. The wires from the PC cord should be taped in place in front of the ball (or just to the side if you don't want the wires in the photograph). Small strips of aluminum foil can be taped to the bare ends of the wires to provide greater contact area. When the ball is kicked, it should force the wires into contact and set off the flash unit. You may want to experiment with the positioning of the wires in order to capture the football at different stages during the kick. Activity 8. Photographing waveforms on an elastic band Additional equipment: Tape recorder sound trigger Large rubber band With a sensitive sound trigger, a snapped elastic band can be observed almost immediately after its release. The tape recorder sound trigger described in Appendix E works particularly well for this. Use a large rubber band or a length of elastic cord. If you use a rubber band, cut it so that you can stretch it end-to-end. Hold the microphone of the tape recorder near the point where the band will be plucked. Aim the flash unit at the band. When the band is plucked and the flash discharges, the initial waveform can be observed.15 To observe the waveform at a later time, move the microphone further from the release point of the cord. If photographs are to be taken, one must be aware that the small size of the subject will fool the flash unit's automatic exposure circuit. The exposure of the film will be determined primarily by the light reflected from the background. This will quench the flash discharge later than needed for correct exposure of the cord. The problem can be minimized by hanging a background (even a dark one) within about a meter of the cord. One could also try photographing a shadow of the cord cast on a white background. Special precaution: Another problem in taking photographs is that the click of the camera shutter may actuate the sound trigger prematurely, giving unwanted exposures. To avoid this, hold a hand over the camera lens while opening the shutter.

For an explanation of the interesting waveforms produced on the cord, see Refs. 9 and 10 in Appendix B.
SECTION III. Photogate Triggers and Delay Units
The common items of equipment for the activities in this section are a Vivitar 283 flash unit and instruction booklet, PC cord, SB-4 adapter, extension cord, flash clamp, camera, film, and background cloth. Additional items for particular activities are listed at the beginning of the corresponding activity. Activity 9. Using an interrupter photogate to observe a plucked cord Additional equipment: Interrupter photogate trigger Elastic cord (approx. 1/8 diameter and 0.5 m long) Two supports for the cord Background: A photogate consists of an emitter and detector of light aimed at each other. The emitter may produce a beam of visible or infrared light. The interruption of the beam serves as the triggering event. The emitter may be a light-emitting diode (LED), a laser, or a beam of white light from, say, a penlight. The detector is a phototransistor, serving as a variable resistor whose resistance depends on the intensity of detected light. Circuit diagrams and parts lists for photogate triggers are given in Appendix F. Two types are described. The one that has a transistor switch will be used in this activity. This trigger has a very rapid
response that will be needed for capturing a fast-moving cord. The photogate itself is an interrupter, described in Appendix F. A photograph of an interrupter being held by a pair of needlenose pliers is shown to the right. One post of the interrupter houses an infrared LED and the other post houses the detector. The two parts face inward across the narrow gap between the posts. When the cord passes between the gap, a flash unit will discharge.
If you did Activity 8, you used a sensitive sound trigger to observe the shape of a plucked, elastic cord. In this activity, the interrupter photogate will be used for observing the shape.16 1. Youll first need to adjust the photogate trigger for maximum sensitivity. Turn the sensitivity knob (or variable resistance) one way or the other until the flash discharges spontaneously. Then back off slightly to the point where the flash will discharge when something is passed through the gap of the interrupter. What you have done is found the threshold for spontaneous triggering. As long as the resistor is just below the threshold, the trigger will be at its most sensitive. Above the threshold, the trigger will not function. 2. Stretch the elastic cord horizontally between two fixed supports as shown in the diagram. Pull the cord upward at the center and hold it steady. Bring the gap of the interrupter down over the cord on one of the diagonal sides so that when the cord is released, it will pass out of the slot and discharge the flash unit. 3. Try placing the interrupter at different positions. This will

The delay (in seconds) is approximately equal to the product of the capacitance (in f) and the setting of the variable resistor (in M). If the meximum value of the variable resistor is 1 M, as in the circuit of Appendix G, then the maximum time delay with a 1-f capacitor is 1 second.
too low, the flash will not discharge at all. Now replace the 1-f capacitor with the 0.1-f one. Is the delay noticeable? Whenever using the delay box, youll need to decide what capacitor to use in order to get best results. 2. Place the contact trigger on a table. Connect the wire leads to the input of the delay box. Aim the flash unit so that it will illuminate a ball as it strikes the table. A squish ball (available at some toy stores) works best for short drops. Use the delay box, with an appropriate capacitor selection, to observe the collision of the ball with the trigger at different times after contact. Some trial and error may be necessary to determine which capacitor is best. The best selection will allow you to scan the entire time interval of the collision--but not much more than that--by turning the variable resistor through its entire range. One problem that you may notice in using the contact trigger is that the flash unit discharges on consecutive bounces of the ball. Turn on the reset delay switch to eliminate these unwanted flash discharges.19 3. Try dropping a water balloon onto the trigger. First, put the contact trigger into a plastic bag with only the wires coming out. Seal the bag well to keep water from leaking into it. Set the trigger on a slightly raised platform in a tray to catch water in case the balloon breaks. You can probably use the same capacitor as for the squish ball. The water balloon takes on an interesting variety of shapes will it is collapsing onto the trigger and also while it is rebounding. Be sure to scan the entire time interval of the collision and a little beyond. Note: You may wish to calibrate the delay unit so that you know the values of the delays for various resistor settings. This can be done by connecting flash units to both of the outputs and measuring the time interval between flash discharges with a high-speed clock. (See Activity 3.) Activity 12. Plucked cords and rubber bands Additional equipment: Bracket photogate Photogate trigger (transistor type) and cord to delay unit Electronic delay unit with selection of capacitors Elastic cord Two supports for the cord

See Appendix G for to find out how different reset delay times are achieved.
Rubber band gun Background: In Activity 9, you used an interrupter
photogate to observe waveforms on a plucked, elastic cord. You achieved different delays by moving the interrupter to various positions along the cord. In this activity, youll use a bracket-type photogate in a fixed position in order to obtain a wider range of delays. The bracket holds the infrared LED and photodetector farther apart than the interrupter, thus allowing larger objects to pass through. 1. In order to observe waveforms on an elastic cord, connect the photogate to the delay unit. Use a 0.01-f capacitor with the delay unit, and connect the flash unit to output 2. Adjust the photogate to maximum sensitivity as described in Activity 9. Set up the arrangement shown to the right. Tape the photogate to the tabletop and stretch the cord between two fixed supports. Pull the cord down into the bracket and release it in order to discharge the flash unit. Adjust the delay in order to show the cord at different times after release. If you need greater delay times, use a larger capacitor. Adding a second 0.01-f capacitor in parallel with the first will double the maximum delay time. 2. If you have a rubber band gun, hold the end of the barrel near the photogate and fire a rubber band through the photogate. Adjust the delay to show the band at various times after it leaves the gun. Activity 13. Photographing splashes Additional equipment: Photogate trigger (Schmitt trigger type) and cord to delay unit Electronic delay with 0.5-f capacitor 2 support stands for LED and photodetector
Milk, dropper, ball, bucket of water or aquarium tank The Schmitt trigger photogate described in Appendix F works best for this activity. Set up a photogate with separate infrared LED and photodetector facing each other about half an inch apart and about a foot above the table top. Connect the output of the photogate to the input of the delay box, and connect output 2 of the delay box to a flash unit. Adjust the photogate for maximum sensitivity. Release a milk drop just above the gate. Adjust the delay so that you can capture the drop as it strikes the table. The 0.5-uf capacitor will provide delays up to about a half second. Since the milk drop is small, you may not be able to get close enough to produce a large image of the splash on film. In order to produce a bigger splash, drop a ball into a bucket of water. By adjusting the delay, you should be able to see the circular wall of water that forms as the ball is breaking the surface. At slightly later times, you may be able to capture the jet of water that rises vertically as the water rushes inward to close the cavity formed by the ball. If you drop the ball into an aquarium of water and aim the flash unit through the side, you can adjust the delay to see the path of the ball in the water. Activity 14. Using a light slave Additional equipment: Electronic delay unit and capacitor selection NPN phototransistor (e.g. TIL414) Second flash unit A light slave is a trigger that sets off one flash unit in response to the flash of light from another. These are often used by photographers to illuminate a subject with more than one flash unit without the need of long cords. The master flash unit may be used on the camera hot shoe and the slave unit positioned to the side. The delay box can serve as a light slave simply by connecting an NPN phototransistor to the input. Connect the emitter to the positive side of the input and the collector to the negative. In this configuration, a flash of light on the transistor will have the effect of dropping the voltage across it, thus triggering the delay circuit. Using the delay box as a light slave makes it possible to interject a time delay between the discharge of the master and slave flash units. Use one flash unit directly on your camera so

that it discharges upon pressing the shutter. Use the second flash unit, connected to output 2 of the delay box, off the camera. Of course, youll have to select a shutter speed long enough so that the slave unit discharges before the shutter closes. And youll have to pick relatively slow-moving objects since you have to trigger the shutter manually. If you have a camera with an electronic shutter release, you may want to try connecting a trigger (contact, sound, or photogate) to the input of the shutter release. In that way, the event that you are photographing will trip the camera. This would make it possible to work in a room with subdued lighting, since the shutter would not be open for long. Keep in mind, though, that for most cameras there is a significant delay (hundredths of a second) between the trigger signal and the opening of the shutter. Note: By using the delay box as a light slave and connecting a single flash unit to output 2, you can cause the flash to trigger repetitively on its own flashes of light. There is, however, a minimum delay which is influenced by the recycling time of the flash unit.
SECTION IV. Measuring Small Time Intervals and High Speeds
In addition to a camera and accessories, the activities in this section require two 283 flash units and accessories. The high-frequency clock described in Activity 3 is needed for timing. While a stroboscope is convenient for frequency measurement, an alternative is described at the end of Activity 15. Activity 15. Speed of sound Additional equipment: 2 piezoelectric sound triggers Meter stick and protractor 2 wooden blocks Note: Before doing this activity, try Problem 1 in Appendix I for practice. 1. For this and the next activity, youll be using two sound triggers and two flash units. Set up the high-speed clock as you did in Activity 3 and measure its frequency. In that activity you were measuring the duration of a single flash. In this activity, youll measure the time interval between two flash discharges to use in determining the speed of sound. Frequency of clock = 2. Connect a sound trigger to each flash unit (in yellow automatic mode) and arrange them so that they illuminate the clock disc. Adjust each trigger for maximum sensitivity. (Note that if the sensitivity is too high, the flash will not discharge at all.) Place both triggers next to each other and stand about a meter away. Clap the blocks together, watching the rotating clock disc while you are doing this. If the two triggers have identical sensitivities, the flash units will discharge simultaneously, giving a single image of the radial line on the disc. If you see two images separated by more than a few degrees, adjust the sensitivity of one trigger until it matches that of the other. (In order to determine which flash discharged first, put a piece of colored acetate film--such as a report cover--over one of the flash units.)

Appendix C. Photographic Basics Selecting aperture (f-stop) If you want to take good high-speed photographs consistently, one thing you need to know is how to select the aperture of your camera lens. On most lenses, the aperture dial has a sequence of numbers 22, 16, 11, 8, 5.6, 4, 2.8, 2, 1.4, 1.0. These numbers are called f-stops and are written f/22, f/16, etc. Some lens won't go as high as 22 and most won't go as low as 1.0. The f-stop is related to the size of the aperture in an inverse way; that is, the larger the fstop, the smaller the aperture. It's useful to know how many times more light one aperture lets in than another. For example, f/4 lets in twice as much light as f/5.6, f/5.6 lets in twice as much as f/8, and f/22 lets in half as much as f/16. Here's a problem showing how you might use this knowledge in flash photography. Problem: Suppose you've determined that f/5.6 is the best f-stop to use for taking a highspeed photograph of a bursting balloon using Kodak Gold 400 film. Another person wants to take a photograph of the same subject, but she has Kodak Gold 100 film. What f-stop should she select? Solution: Each film has an ISO rating which indicates its sensitivity to light. (Gold 400 has ISO 400 while Gold 100 has ISO 100.) ISO 400 film is four times as sensitive to light as ISO 100. This means that the ISO 100 film requires four times as much light to produce the same exposure as the ISO 400 film. The way to get four times the light is to open the aperture wider. f/4 would give twice as much light as f/5.6. Using f/2.8 would give another factor of two more light. Altogether, that would be 2x2 = 4 times as much light. Depth-of-field The aperture that you select for a photograph affects two things: 1) the exposure of the film and 2) the depth-of-field. Depth-of-field refers to the range of distances in front of and behind the subject that will be in acceptable focus in the photograph. There are two ways to increase depth-of-field when using a particular lens: a. use a smaller aperture (larger f-stop), b. move farther from the subject, Suppose that you're photographing a balloon burst and you want the balloon to be in focus from front-to-back. You may not want to move too far from the balloon, because you want it to appear large in the photograph. That means you would need to use a smaller aperture. This may require you to use a more sensitive film, that is, one with a larger ISO rating. (See problem above.)

Appendix F. Photogate trigger circuits Two circuits are described. Each uses an infrared emitter and detector. (A penlight can provide a substitute for the infrared emitter, even when using an infrared detector.) The transistor switch has a very rapid response and is good for triggering on fast-moving objects. The Schmitt trigger works better for slow-moving objects such as a milk drop falling through the photogate. There are many infrared emitters and photodetectors that can be used with these circuits. The ones that are given in the parts lists are usually available from Radio Shack. An interrupter is a device that includes both an emitter and detector in a single, molded-plastic package. An interrupter is useful when the object that breaks the infrared beam is narrow, since the gap between detector and emitter is only about an eighth of an inch. One possible interrupter that can be used with either circuit is given below.22 A. Transistor switch A photogate trigger circuit that uses a transistor is shown to the right. The 2N2222 transistor acts as a switch in the gate-cathode path of an SCR. The SCR is connected either to a flash or delay unit (see Appendix G). As long as the phototransistor is illuminated by the LED, the collector-emitter path of the 2N2222 is open. When the light is blocked, the voltage across the phototransistor rises and the 2N2222 conducts, thereby gating the SCR. (See Appendix D for an appropriate SCR.) The sensitivity of the photogate is controlled with the 100-k variable resistor.23 This is an important feature for detecting small, fast objects and allowing large separations between the detector and emitter. For maximum sensitivity, the resistance is adjusted low enough to raise the voltage across the phototransistor to the threshold of triggering. Whenever the detector-emitter separation is increased, the resistance must be increased, since the phototransistor's own resistance rises as the illumination on it decreases.
An interrupter available from Digi-Key (see footnote in Appendix D for address) is part no. H21A1QT-ND. A variable resistor with a smaller range could be used for finer control at high sensitivities.
Parts list for transistor switch Infrared emitter (XC-880-A) Infrared phototransistor (TIL414) 2N2222 transistor 9-V battery and clip B. Schmitt trigger The transistor trigger may not respond well to slow-moving objects such as falling liquid drops. A Schmitt trigger provides an alternative.24 The circuit uses a 555 timer IC, shown on the next page. When the light from the emitter to the phototransistor is blocked by a moving object, the voltage across the phototransistor increases. When it reaches a certain level, a square, 9-V output pulse is produced at pin 3, thus gating an SCR. (See Appendix D for an appropriate SCR.) The sensitivity is adjusted with the 5-k variable resistor.25 For lower values of this resistance, the value of the phototransistor's resistance that results in triggering will also be lower. This means that triggering will occur with less blockage of the light beam. Or, if the emitter-detector separation were greater, giving a lower intensity at the detector, the variable resistance would have to be greater in order to prevent spontaneous triggering. 470- resistor 10-k resistor 400-V sensitive gate SCR 100-k variable resistor

The circuit is modified from the one given in Ref. 11 of Appendix B. A variable resistor with a larger range may be needed as detector-emitter separation is increased.
Appendix G. Electronic delay circuit The delay circuit shown to the right is adapted from the cascaded timer circuit described in Ref. 12 of Appendix B. A 556 timer, consisting of two 555 timers, is used. When the input is grounded or a negative input pulse provided, output 1 goes high. It remains high for a length of time that is determined by the setting of the 1M variable resistor and the value of the capacitance, C. At the end of that time, output 2 goes high, remaining high for about 10 ms. This time, termed the reset delay, is determined by the 10-f capacitor and 1 k resistor. The reset delay is normally small enough to allow the flash unit to be triggered repeatedly with minimal delay. If a greater delay is desirable, the 1 kresistor can be replaced with, say, a 100-k resistor. When used with a photogate or sound trigger to discharge a flash unit, the output of the trigger becomes the input of the delay circuit. Either or both of outputs 1 and 2 can be used to trigger flash units. Output 1 is immediate, and output 2 is delayed. Try building the circuit on a breadboard first. Later, you may want to transfer it to a circuit board and put it in a project box with an on-off switch, input and output terminals, and a selector for capacitance. Parts List In addition to the parts listed below, several capacitors (0.01-1.0 f) are needed to provide different time ranges. (This would be the value for C in the circuit diagram.) See Appendix D for appropriate SCRs. 556 timer IC 2 400-V sensitive gate SCRs 9-V battery and clip 1-M variable resistor Resistors: 1 1-k, 1 100-k, 1 1-M, 4 22-k Capacitors: 2 0.005-f, 2 0.05-f, 1 10-f
Appendix H. Making a contact trigger Here is one way to make a contact trigger. Begin by assembling the following supplies: 2 20-cm squares of stiff cardboard (1-2 mm thick) 2 20-cm squares of aluminum foil 1 20-cm square of black construction paper or poster board Glue and tape 2 1-m wire leads Now do the following: 1) Smooth any wrinkles out of a 20-cm square of aluminum foil. Then glue the foil to the same size stiff cardboard. Tape the bare end of a 1-m wire lead to one corner of the foil. 2) Smooth out another 20-cm square of aluminum foil and glue it to black poster board or construction paper of the same size. Tape another 1-m wire lead to a corner of this foil. 3) From a second 20-cm square of stiff cardboard, cut out a 15-cm square hole, leaving a square frame of 2.5 cm width. Glue this frame onto the foil prepared in step 2). 4) Arrange the various pieces as shown in the diagram below. Notice that the cardboard frame acts as a spacer to separate the pieces of foil. If an object is dropped onto the upper piece, it will be forced into contact with the lower.

Appendix I. Problems in high-speed measurement Problem 1. High-speed clocks a. Clocks with rotating hands measure time in terms of the angle swept out by the hand during the time interval. Representing the angle as and the period of the hand as T, write an equation for the time interval, t, in terms of and T.
The photograph to the right shows two rotating discs, A and B. Although each disc has a single hand, two images of the hand are seen because the discs were lit by sequential bursts of light from two flash units. The frequency of disc B was measured with a stroboscope and found to be 50.5 rotations per second. b. Determine the time interval between the bursts of light. Also estimate the uncertainty in your result, based on the accuracy and precision of your measurement of angle.
c. Determine the period of disc A.
Problem 2. Speed of a balloon rip The figure below shows a double-exposure of a balloon rip taken according to the method of Activity 17. The frequency of the clock was 51.7 rotations per second, and the diameter of the disc was 0.105 m.
a. Measure the angle swept out by the clock hand and calculate the time interval between the flashes of light.
b. Measure the diameter of the clock disc on the photograph and calculate a scale factor to be used in converting distances measured on the photograph to actual size.
c. Measure the distance between the two images of the rip vertex. Then use the scale factor to convert to actual size.
d. Calculate the speed of the rip.
e. Estimate the uncertainties in your measurements of distance and time. Use them to estimate the uncertainty in the measurement of speed.
