Answer 2

Answer:

A shadow is a dark area where light from a light source is blocked by an opaque object. It occupies all of the three dimensional volume behind an object with light in front of it. The cross section of shadow is a two dimensional sillhouette, or a reverse projection of the object blocking the light.
