What is refraction: Refraction is when light changes

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. Refraction of light is one of the most commonly observed phenomena, but other waves like sound waves and water waves also experience refraction. Refraction makes it possible for us to have optical instruments such as magnifying glasses, lenses and prisms. Discover the principles of refraction of light for Class 10 Physics, including Snell's law, refraction through glass slabs, and the effects of medium change. Includes step-by-step diagrams, real-life examples, and key questions. 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.
