shadow 

A darkened area from which rays from a source of light are excluded. The shadow pattern cast by light (e.g. sunlight, ceiling fixtures) is such a common sight that if light shines from the opposite direction (e.g. from the ground upward) the normal shadow pattern will be reversed and so will perception; depressions will appear as mounds or vice versa. Shadows offer a cue to depth perception, as when trying to judge the shape of objects. See penumbra; depth perception.
