A light ray travels through medium 1 , index of refraction \(n_{1}=1.5\), into medium 2, index of refraction \(n_{2}=2.4\) (Figure P33.55). At what angle with respect to the normal to the interface between the media does the light need to strike the interface so that the reflected and the refracted rays are at right angles to each other?
