Why Does Light Refraction Occur?

Answer

Light refraction occurs due to the passage of light through or across the boundary of two media of varying refractive indices. It is at the boundary that the light wave will change direction, which will be accompanied by a change in both speed and wavelength of the wave.

Light refracts because it travels at different velocities. Light also refracts because various colors of light travel at different speeds.

For this explanation we need to consider light travelling as a series of 'wave-fronts' rather than as rays (a line of sea waves approaching a beach form straight wave-fronts) Wave-fronts
