Question:

A light ray in the core (n = 1.40) of a cylindrical optical fiber travels at an angle θ1 = 49.0° with respect to the axis of the fiber. A ray is transmitted through the cladding (n = 1.20) and into the air. What angle θ2 does the exiting ray make with the outside surface of the cladding?
