Question

The index of refraction of Lucite is 1.49. At what angle of incidence will the reflected light be totally polarized? You are standing on the sidewalk on Pacific Avenue. You notice looking toward a shop window the reflection of a person of your height walking toward you. The reflected light is partially polarized. Is it polarized vertically, horizontally, or somewhere in between? Explain your reasoning. You now see the image of another person, reflected from a puddle on the sidewalk. The reflected light is partially polarized. Again, is the light polarized vertically, horizontally, or somewhere in between? Explain your reasoning.

Explanation / Answer

Problem 2)

from Brewsters law, we have
? = tan(p)
or p = tan-1(?)
given lucite has index of refraction ? =1.49

p = 56.13 degree
