Shadow

A shadow is the dark area or shape produced when an object blocks light from a source. When light encounters an opaque object, it cannot pass through, creating a region behind it where the light is obstructed. This results in a shadow, which mirrors the shape of the object but is typically darker than the surrounding areas. Shadows help us perceive depth, direction, and the position of objects relative to the light source. Their size and length vary depending on the angle and intensity of the light. Essentially, shadows are visual indicators of how light interacts with objects in our environment.
