Answer:-
The incident ray,the refracted ray and the normal to the interface of two transparent media at the point of incidence, all lie in the same plane
The ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of a given colour and for the given pair of media
Laws of Reflection :
Snell's law
μ 1 sini = μ2sinr.

The change in direction of light when it passes from one medium to another, is called the Refraction of Light.
Law 1. - The incident ray, the normal at the point of incidence and the refracted ray, all lie in the same plane.
Law 2. The ratio of the sine of angle of incidence to the sine of angle of refraction for a given pair of media and for a given colour of light is constant. The constant is known as the refractive index.
