Explanation:
Shadows most often appear black because the visible light cannot make its way past the obstruction, if there is no light falling on an object then it will be black as there is no light to reflect.

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.
