1. The problem statement, all variables and given/known data You are walking down a long hallway that has many light fixtures in the ceiling and a very shiny, newly waxed floor. In the floor, you see reflections of every light fixture. Now you put on sunglasses that are polarized. Some of the reflections of the light fixtures can not longer be seen. The reflections that disappear are those: Nearest to you Farthest from you At an intermediate distance from you Both nearest & farthest 2. Relevant equations $$\mu = tan(i_b)$$ 3. The attempt at a solution I think the answer should be (3) and is indeed the case. However, I am not sure about the reason. I think it should be this way because rays from only a few sources at an intermediate distance will be incident at an angle equal to ##i_B##. Is this correct?
