1. The problem statement, all variables and given/known data A corner reflector is to be made from a triangular prism with index of refraction n = 1.90, as shown in the diagram below. What is the maximum angle, with respect to the normal to the front surface of the prism, (theta), such that total reflection will occur? http://capa.sci.geneseo.edu/teacher/capalibrary/Graphics/Gtype73/prob02.gif (link to image) 2. Relevant equations sin(critical angle)=(n1/n2) 3. The attempt at a solution Tried using that equation, failed miserably.
