the complete reflection of a light ray reaching an interface with a less dense medium when the angle of incidence exceeds the critical angle is known as total internal reflection.
its three conditions are:
The index of refraction must decrease across the boundary in the direction of light refraction.
The angle of incidence of the light ray must exceed the critical angle of the interface.
Ray must travel from denser to rarer medium.
