Question

what is refraction write the laws of refraction long answer
​

Answer 1

Answer:

1. the incident ray, the refracted ray and the normal to the interface of two media at the point of incidence all lie in the same plane.

2. For the light of a given color and for given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant.

Answer 2

Answer:

When the light passes from one transparent medium to another by changing its velocity is called as refraction
