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.
No the color of the light will not affect the shadow because .Shadow is the dark patch formed when an object obstructs the path of the light. Hence no light reaches in the shadow region; due to which the color of the shadow is black. Hence the color of light will not affect the shadow color because light is obstructed by an opaque object.
