Unoccupied Pool:
a) At what angle of reflection is the sunlight reflected off the smooth surface of an object with a refractive index for the light that is completely polarized?
b) What is the corresponding angle when the light is turned on in the pool?
c) At night, an underwater floodlight transmits (refracts) the floodlight that strikes the smooth surface from below. Repeat parts a) and b) for rays from below.
