The angle and wavelength at which the light enters a substance and the density of that substance determine how much the light is refracted. ... The bending occurs because light travels more slowly in a denser medium.
[It occurs due to the differences in density between two media]

→Refraction is the bowing of light (it too happens with sound, water and other waves) because it passes from one straightforward substance into another. This twisting by refraction makes it conceivable for us to have focal points, amplifying glasses, crystals and rainbows.
