Question

3) State the laws of refraction of light.​

Answer 1

Answer:

a)the angle of incidence should always be equal to the angle of reflection.

b)the incident ray , the reflected ray and the normal should lay on same plane.

hope it helped you

Answer 2

Answer:

1. The incident ray , refracted ray and normal to the interface of two transparent medium 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 is constant , for the light of given colour and for the given pair of media
