Question

IS NECSSERY FOR THE INFORMATION OF A SHADOW

Answer 1

Answer:

A source of light and a flat, opaque surface is necessary for the formation of a shadow

Explanation:

This could be explained through the following-

Stand in the sunlight and observe your shadow on the ground.

This concludes that a source of light (i.e. sun here) and flat surface (ground here) is necessary for the formation of a shadow. Without the either of the two, it is not possible for a shadow to be formed.
