Question

A student covered a torch with 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 colour of the light affect the shadow ? Explain.

Answer 1

Maim The color of light will not affect the shadow because the shadow is the dark patch r formed when an object obstructs the path of light and hence no light reaches the shadow region.
