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.
The shadow of any object does not depend on the colour of the light. As we know that shadow is the result of the absence of light. When light does not pass through the object, then the shadow is formed due to the absence of light. Shadow depends on the size of the object. jitna bada object hoga utni hi badi uski chaya hog and vice versa.
