Question

State the laws of refraction.

Answer 1

There are two laws of refraction.The laws are:
1.The Incident Ray,the normal and the Refracted Ray at the point of incidence lie on the same plane.
2. For any given pair of media the ratio of sine of angle of incidence and sine of angle of refraction is a constant.
                $\frac{sin i}{sin r}$ =μ constant.
 The second Law is also known as Snell's Law. 

Answer 2

The Incident Ray,the normal and the Refracted Ray at the point of incidence lie on the same plane thiss is the law
