Laws of reraction:
1. The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane.

2. For any two given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is called snell's law.
