Detailed explanation-1: -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 have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light.

Detailed explanation-2: -Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and openings. The amount of diffraction increases with increasing wavelength.

Detailed explanation-3: -Bending of light is the change in direction of a beam of light when it reflects off a surface. The bending of light is a phenomenon that occurs as light moves from one medium to another. Light travels more slowly in denser mediums, causing the beam to arc or bend.
