Why does refraction occur?
Asked by gspublicschool | 23rd Feb, 2019, 12:55: PM
When the light rays are on the boundary of two media (let's say water and air) there is not only a change in the speed of light but also in the change in the wavelength. This results in the change in the direction of light. This change in speed and wavelength of light causes refraction of light.
