Question

what happen to light when the angle of incidence is greater than critical angle
​

Answer 1

Explanation:

This angle of incidence is known as the critical angle; it is the largest angle of incidence for which refraction can still occur. For any angle of incidence greater than the critical angle, light will undergo total internal reflection.

Answer 2

Answer:

total internal reflection occurs

the angle of incidence is greater than the critical angle. When the angle of incidence is greater than the critical angle, the light ray is reflected at the boundary of the two media and total internal reflection occurs. Each pair of media have their own unique critical angle.
