1. The problem statement, all variables and given/known data
A 45,45,90 glass triangular prism (n=1.52) is surrounded by air. If a light ray comes in to one of the legs (not hypotenuse) at a right angle which legs have total internal reflection? 2. Relevant equations n_1sinx_i=n_2sinx_r 3. The attempt at a solution i figured out that the light ray on the first incident leg transmits light to hypotenuse at but am getting confused on how to get the reflection angle at the hypotenuse to figure out how light hits the other leg Edit: the light comes in at the arrow at a right angle. What happens to light at side b and c in the attached pic

The angle of incidence i = 0^{o} since the ray comes at right angle.
