Question

state law of refraction​

Answer 1

Answer:

the incident ray, the refractive ray and the to the interface of transparent media at the point of incidence, all lie in the same plane.

the ratio of sine of incidence to the sine of angle of refraction is a constant for a given pair of media.

sin i/sinr= constant.

Answer 2

The incident ray, refracted ray and normal to the interface of two transparent media at point of incidence, all lie in the same plane. The ratio of sine of angle of incidence to the sine of angle of refraction for the light of a given colour and a given pair of media is a constant. This is also known as snell’s law of refraction.
