Question

what is critical angle

Answer 1

Critical Angle- The angle of incidence beyond which rays of light passing through a denser medium to the surface of a less dense medium are no longer refracted but totally reflected.

Answer 2

Heya user !!!

Here's the answer you are looking for

If the light is incident at certain angle that the refracted rays travels along the interface of the two media then the angle is said to be critical angle. The incident light if travels from a denser medium to rarer medium then critical angle can be seen.
