Laws of Refraction:
There are two laws of refraction.
The incident ray, the refracted ray and the normal to the surface of the point of incidence all lie at the similar plane.
The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing from single medium to another medium. This constant is known as refractive index.
