Question

A student covered a torch with a red cellophane sheet to obtain red light. Using the red light she obtains a shadow of an opaque object. She repeats this activity with green and blue light. Will the color of the light affect the shadow? Explain.

Answer 1

Shadow:

1. No, the color of the light has no effect on the shadow.
2. A shadow is a dark patch that forms when an object blocks the path of light.
3. As a result, no light reaches the shadow region, resulting in a black shadow. Because light is obstructed by an opaque object, the colour of light has no effect on the color of the shadow.
