Explanation:
Causes of Refraction
A light ray refracts whenever it travels at an angle into a medium of different refractive index. This change in speed results in a change in direction. ... When light travels from a less dense substance to a denser substance, the refracted light bends more towards the normal line.
Laws of refraction state that: The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also known as Snell's law of refraction.
