1. The problem statement, all variables and given/known data 5) A beam of monochromatic light enters an equilateral triangular prism at an angle of incidence of 30.0º. If the index of refraction of the prism is 1.53, at what angle with respect to the surface of the prism does the beam emerge from the other side of the prism? 2. Relevant equations 3. The attempt at a solution i tried drawing it out, but i have absolutely no idea.
