Unformatted text preview: critical angle for total internal reflection. Let θ1 be the angle of incidence for the original incident ray and θ2 be the angle of refraction at the first face, and let θ3 be the angle of incidence at the second face. The law of refraction, applied to point C, yields n sin θ3 = 1, so sin θ3 = 1/n = 1/1.60 = 0.625 ⇒ θ3 = 38.68°. The interior an...
