Light travels in a straight line. When all three holes are aligned in same position, we can see the light source. If the three holes aren't aligned, we won't be able to see the light source. This proves that light movement is linear.
Activity:
- Insert two dry cells into the kit.
- Prepare the equipment as shown in the picture.
- Fit in the bulb and see through the screen. Can you see the light?
- Move one of the screens to other position. Can the light still be seen? This is because the holes are not aligned.
