what is retraction of light
Answers
Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. ... Refraction is responsible for image formation by lenses and the eye.
in physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.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 refractionmakes it possible for us to have lenses, magnifying glasses, prisms .
