Answer:
A shadow is a dark (real image) 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 a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.

characteristics
There are strong edges on the shadow borders
The shadow is ‘darker’ than the surrounding area
The shadow usually ‘deforms’ when an object is rotated
Due to absence of the primary lighting in the shade, the color tends to be dominated mostly by the main diffuse lighting source (which is in most cases the sky --> blue)
