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 a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light. WebThe shadow of a body is the region where the light of the source doesn't arrive so since their isn't any photon (assuming that the body is 100% opaque) in the shadow, we shouldn't be able to see it. The only reason we see the shadow is by the contrast effect with the surrounding which reflects or scatters light.

Webabsorption, in wave motion, the transfer of the energy of a wave to matter as the wave passes through it. The energy of an acoustic, electromagnetic, or other wave is proportional to the square of its amplitude—i.e., the maximum displacement or movement of a point on the wave—and, as the wave passes through a substance, its amplitude steadily …
WebDiffraction of light is defined as the bending of light around corners such that it spreads out and illuminates areas where a shadow is expected. In general, it is hard to separate diffraction from interference since both … WebA shadow is a dark shape that is formed when an object blocks a source of light.
