An incident beam consisting of white light (falsely colored as an orange ray) passes through a quadrilateral prism, like the one shown in the figure below. What is the angle η of the outgoing beam? Assume the prism’s index of refraction is n = 1.72. Just to be clear, the angles at each of the vertices of the quadrilateral prism are 78.7o, 107o, 113o, and 61.3o. The angle of incidence is 27.0
