state laws of refraction
Answers
1) The incident ray, the refracted ray and the normal to the interface of the two media at the point of incidence all lie on the same plane
2) The ratio of sine of angle of incidence to the sine of angle of refraction is a constant value for a given pair of media and for a light of a given colour.
This constant value is known as the refractive index of the second medium with respect to the first medium
