The figure below shows the path of a beam of light through several layers with different indices of refraction. (Assume n = 1.02.) n = 1.60 n = 1.40 n = 1.20 02 14 (a) If 0₁ = =28.0°, what is the angle 2 of the emerging beam? (b) What is the smallest incident angle ₁ to have total internal reflection at the surface between the medium with n = 1.20 and the medium with n = 1.02?
