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. Learn about refraction in physics. Get its definition and explore Snell's law and the index of refraction. Get examples for light and sound. Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to... What Is Refraction? Refraction of Light is a phenomenon wherein light bends and travels from one transparent substance to another. Let’s understand this concept in-depth with an illustration. So, have you ever observed the bottom of a thick glass slab when a printed paper is kept below it? You will find that the printed matter seems to be raised. Similarly, when a pencil is partly immersed in water in a glass tumbler, it appears to be displaced from its original position at the surface ...
