Question

A right angled prism is to be made by selecting a proper material and the angles A and B (B $\leq$ A), as shown in the figure. It is desired that a ray of light incident on the face AB emerges parallel to the incident direction after two internal reflections.For n = $\frac{5}{3}$, is it possible to achieve this with the angle B equal to $30\°$?
