Theres one angle of incidence b onto a prism for which the light inside an isosceles prism travels parallel to the base and emerges at angle b. a. Find an expression for b in terms of the prisms apex angle a and index of refraction n. b. A laboratory measurement finds that b = 52.2 for a prism shaped like an equilateral triangle. What is the prisms index of refraction?
