A shadow is a two-dimensional region of space from which light is blocked and hence within which light is absent due to the presence of a three-dimensional object coming between the region and the light source. A shadow is therefore a kind of absence: light is not merely absent from the region, but the shadow is itself an absence of light that spatially marks out the region.
