Question

Are there conditions under which the incident light ray undergoes reflection but not transmission at the boundary? if so, then what are those conditions?

Answer 1

Total internal reflection causes light to be completely reflected across the  boundary between the two media but not transmitted.

What is total internal reflection?

The term total internal reflection occurs when light is moving from a denser to a less dense medium such as from glass to air. This phenomenon occurs at the interface between the two media.

There are two conditions necessary for total internal reflection and they are;

1) Light must travel from a denser to a less dense medium

2) The angle of incidence in the denser medium must be greater than the critical angle.
