In Fig. 33-78, where n 1 = l.70, n 2 = l .50, and n 3 = 1.30, light refracts from material l into material 2. If it is incident at point A at the critical angle for the interface between materials 2 and 3, what are (a) the angle of refraction at point B and (b) the initial angle θ ? If, instead, light is incident at B at the critical angle for the interface between materials 2 and 3, what are (c) the angle of refraction at point A and (d) the instead angle θ ? If, instead of all that, light is incident at point A at Brewster’s angle for the interface between materials 2 and 3, what are (e) the angle of refraction at point B and (f) the initial angle θ ?
