In Figure, where n₁= 1.70, n₂= 1.50, and n₃= 1.30 light refracts from material 1 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 initial 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?
