Shadows

Shadows are dark areas created when an object blocks light from a source, such as the sun or a lamp. When light travels in straight lines, it cannot pass through opaque objects, leading to the formation of a shadow behind them. The size and shape of a shadow change depending on the light source's angle and distance from the object. For instance, at noon, shadows are shorter, while in the morning or evening, they are longer. Understanding shadows is important in areas like art, photography, and even science, where they can indicate the position of light sources.
