Item 7 Part A Light is incident along the normal to face AB of a glass prism of refractive index 1.52, as shown in the figure. (Figure 1) Find max, the largest value of the angle a such that no light is refracted out of the prism at face AC if the prism is immersed in air. Express your answer in degrees. Ignore any reflections from the surface BC. View Available Hint(s) AEd ?
