Question

Write Laws of refraction of Light​

Answer 1

Laws of refraction state that:

1. The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane.
2. The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.
