1 All About Shadows Topic Light travels in straight lines Introduction It may seem a strange idea that light travels only in straight lines, but it would be even odder if it were able to curve around objects in its path to illuminate them from behind. Where would we be without our shadow the area of darkness behind us where our body blocks out the rays of light from the Sun? You can estimate the time of day by judging the length of shadows; shadows decrease in size towards midday when the Sun is high in the sky, and increase in length as the Sun sinks to the horizon. In this experiment, you will make shadows using electric light as a source of light. You will then find out how to make shadows larger and smaller. This experiment and others in this section require a narrow, concentrated beam of light (a ray of light) whose path remains visible for at least 0.5 meter and which does not splay out (or diverge) at the sides. This is achieved using a piece of equipment known as a light box or a ray box or a ray optics box. If you do not want to purchase a light box like the one shown in diagram 1 below, you can make one using the instructions given for Part A below. 1 metal casing surrounding light bulb lead to electrical outlet slot for color filter collimating lens (to concentrate light rays so that they travel in straight lines) slit plate with single and triple slits Purchased light box Time required 30 minutes for Part A 30 minutes for Part B 30 minutes for Part C Materials NB: Part A materials are only required for students constructing their own light box.
2 For Part A: 8 1 /2 11 sheet of black poster board craft knife or X-acto knife 30 cm ruler pencil small, powerful flashlight such as mini Maglite ( double-sided tape or re-usable adhesive putty translucent tape scissors cutting board For Parts B and C: light box minus its slit plate (the small light source ) 60 watt light bulb with a tungsten filament (do not use a low energy bulb or a spotlight) supported in a bulb holder (the large light source ) piece of white, unlined index card, about 3 cm high, cut to whatever shape you like (the object ) 4 cm sewing needle 1 2 cm of cork cut from a wine bottle cork cardboard (e.g., from a large cereal box) about 30 cm 40 cm to form a screen 2 stands and ring clamps (to support the screen ) meter ruler 2 sheets of white, unlined 8 1 /2 11 paper table (at least 0.6 m wide and 1.2 m long) translucent tape pencil Safety note Cut and score the poster board in Part A on a work surface protected by a cutting board. Do not stare directly into bright light sources. Do not touch the light box or the light bulb when switched on. Procedure Perform this experiment in a room where you can restrict external light, i.e., the windows can be covered. Begin all parts of the experiment with windows/blinds closed and the room lights on. Part A: Constructing a simple light box Those with a purchased light box can omit this part of the experiment. 1. With your pencil and ruler, mark out the template shown in diagram 2 on the next page on the piece of black poster board.
3 2 single slit end piece top 4.5 cm triple slit side 5 cm end piece base 4.5 cm 5.5 cm side 5 cm overlap Template for light box 2. Using scissors, cut along the solid lines to give two pieces of poster board. Then cut out the two end pieces of the box from the smaller piece of poster board. (The end pieces are slightly larger than the end of the box to allow them to be attached firmly and thus stop light escaping around the edges of the box.) 3. Using the lines on the template in diagram 2 above as a guide, cut the slits in the end pieces with the knife. Use the ruler to ensure that the lines are straight. 4. Using the knife and the ruler, carefully score along the dotted lines on the large piece of poster board. Fold it to form a box and secure with translucent tape. 5. To produce a single ray of light, place the single slit end piece over one end of the box with the open end of the slit at the base of the box. Attach firmly with translucent tape around the sides, making sure that no light can escape around the edges of the end piece. Your box should look like the one in diagram 3 below. To produce three parallel rays of light, use the end piece with three slits. 6. Turn on the flashlight. Put it inside the open end of the box so that it shines toward the end piece (see diagram 4 on the next page). 7. Turn off the room lights. Adjust the position and angle of the flashlight until the ray of light coming through the slit is seen clearly. If necessary, secure the flashlight in place with tape or putty. Turn on the room lights. 3 front view single slit end piece Front view of light box translucent tape securing end piece firmly to the end of box

Tape the card shape to the needle. Stick the needle into the piece of cork so that the shape is supported upright to form the object whose shadow you are studying. 2. Secure the screen in an upright position using the clamps and stands. 5 clamp sheet of paper taped to screen screen stand card shape light box ( small light source ) needle 30 cm meter ruler 30 cm cork table Arrangement of light source, object, and screen
5 3. Place the meter rule on the table. Position the light box, the object, and the screen along the rule as shown in diagram 5 on the previous page. (NB: This shows the purchased light box.) 4. Tape one of the sheets of paper to the screen so that it is facing the light source, and in line with the light source and the object (as in diagram 5 on the previous page). 5. Turn on the light and turn off the room lights. 6. Using the pencil, draw around the shadow on the piece of paper on the screen. Label small light source. 7. Turn on the room lights and turn off the light. 8. Replace the small light source with the large light source and repeat steps 5 to 7, labeling the shadow large light source. Part C: Factors affecting the size of shadows 1. Arrange the small light source, the object, and the screen as in diagram 5 on the previous page, but with the other piece of paper. Turn on the light source and turn off the room lights. 2. Draw around the shadow formed on the screen, labeling the shadow position 1. Turn off the light source and turn on the room lights. 3. Move the object to a point 15 cm from the light source. Turn on the light source and turn off the room lights. 4. Repeat step 2, labeling the new shadow formed on the screen position Move the object to a position 15 cm from the screen. Turn on the light source and turn off the room lights. 4. Repeat step 2, labeling the new shadow formed on the screen position 3. Analysis Part B: Making shadows with a large and a small light source 1. Describe the shadow formed by the small light source. 2. Describe the shadow formed by the large light source. 3. Were the two shadows the same size? Part C: Factors affecting the size of shadows 1. Was the shadow at position 2 larger or smaller than the shadow at position 1? 2. Was the shadow at position 3 larger or smaller than the shadow at position 1? Want to know more?

6 Part A: Constructing a simple light box The box needs to be long enough to allow the flashlight to be some distance from the slit(s) forming the beam(s) of light in order to decrease the tendency for the beam to splay out at the sides and to enable the beams produced by the triple slit to stay parallel to each other. However, the strength of the light from the flashlight diminishes when it is further from the slit, so a compromise may be necessary between the strength of the beam and the amount by which it splays out at the sides.
7 Black cardboard is used to make the box to minimize internal reflections; most of the light reaching the front of the box thus is thus traveling in straight lines from the flashlight. It is important that light only leaves the box through the slit(s) in the end piece, so this must be fixed firmly onto the box. When the flashlight is placed inside the box, some experimentation will be necessary to find the best angle at which the flashlight should be positioned to produce the best effect (i.e., strong beam with no divergence). Part B: Making shadows with a large and a small light source 1. The shadow formed by the small light source should be a dark shape with clearly defined edges (see the diagram below). small light source object light rays screen darker area of shadow of object Shadow formed using small light source 2. The shadow formed by the large light source should be a gray shape (or even appear as a series of gray shapes) with blurred edges (see the diagram below). 3. The entire shape of the blurred shadow from the large light source (the outer edges are very pale) should be slightly larger than the crisp shadow formed by the small light source. (This is not easy to see; it helps if the room is as dark as possible.) This occurs because the light is illuminating the object from a larger area as shown in the diagram on the next page; overlapping images are formed by light from various parts of the light source. screen large light source object paler area of shadow darker area of shadow paler area of shadow Shadow formed using large light source Shadows formed by the Sun Although the Sun is a very large light source, it is so far away from the Earth that the light rays reaching Earth are considered to be traveling in parallel, rather than diverging from a point. If you look at the shadows formed by the object outside in the sunshine (see the diagram on the next page), you will see that these shadows can have sharp edges (they become more blurred as the object is moved away from the screen).
8 object shadow parallel rays of light from the sun screen Shadow formed by parallel rays of light from the sun Part C: Factors affecting the size of shadows 1. The shadow formed at position 2 is larger than the one formed at position 1. As the object moves closer to a light source, it intercepts more of the light emitted from the source. 2. The shadow formed at position 3 is smaller than that formed at position 1 because an object further from a light source intercepts less of the light emitted from the source. If you repeat Part C in sunlight, you will see that the shadow does not change in size. Instead, it becomes more blurred as the object is moved further from the screen.
