Question 25
H

A ray travels through glass surrounded by air. The critical angle is 41∘41^\circ41∘. At the first boundary, its angle of incidence is 50∘ 50^\circ\,50∘ and it is totally internally reflected. It then meets a second boundary at 55∘ 55^\circ\,55∘ to the surface. Which describes the angles and behaviour at the two boundaries?
