In Fig. 33-64, a light ray in air is incident on a flat layer of material 2 that has an index of refraction n 2 = 1.5. Beneath material 2 is material 3 with an index of refraction n 3 . The ray is incident on the air–material 2 interface at the Brewster angle for that interface. The ray of light refracted into material 3 happens to be incident on the material 2–material 3 interface at the Brewster angle for that interface. What is the value of n 3 ? Figure 33-64 Problem 70.
