In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. [1] . Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. Refraction is when light changes direction and wavelength as it travels through different media. Learn the definition, laws, examples, and applications of refraction, such as lenses, prisms, rainbows, and water waves. In simple terms, when a beam of light travels from one transparent medium to another—like from air into glass or water—its path bends. This bending phenomenon, called refraction of light, not only shapes everyday experiences but also underlies critical technologies and natural wonders.
