The phenomenon created when light bends through water is known as refraction. Refraction occurs when light passes from one medium into another, causing a change in its speed and direction. When light enters water from air, it slows down and bends, leading to various visual effects, such as the distortion of objects partially submerged in water or the creation of a rainbow when light passes through raindrops. This bending of light is an essential principle in optics and is responsible for the functioning of lenses in glasses and cameras, making it a fascinating aspect of both science and everyday life.
