Question

what will happen to the light if the angle of incidence is less than critical angle ​

Answer 1

Answer:

when the angle of incidence is less than critical angle then the ray of light partly and partly refracted.We get weak reflected ray and a strong refracted ray.

Answer 2

Explanation:

For any angle of incidence less than the critical angle, part of the incident light will be transmitted and part will be reflected. The normal incidence reflection coefficient can be calculated from the indices of refraction.
