Question

what are laws of refraction...​

Answer 1

Answer:

Laws of refraction state that: 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.

Explanation:

follow me!!!!

Answer 2

There are two laws of refraction:-

1. The incident ray , the refracted ray and the normal at the point of incidence , all lie in the same plane.
2. The ratio of sine of angle of incidence to the sine of angle of refraction constant for a given pair of media.

• Sin i / sin r = constant. In this i is incident and r is refracted.
