Question

State the first law of refraction of light​

Answer 1

Answer:

Refraction of light is the change in direction (bending of light rays) when it passes from one optically transparent medium to another. ... First law of refraction states that the incident ray, the refracted ray and the normal to the interface all lie in the same plane.

Answer 2

Explanation:
