Some glasses used for viewing 3D movies are polarized, one lens having a vertical transmission axis and the other horizontal. While standing in line on a winter afternoon for a 3D movie and looking through his glasses at the road surface, Maurice notices that the left lens cuts down reflected glare significantly, but the right lens does not. The glare is minimized when the angle between the reflected light and the horizontal direction is 37°.
(a) Which lens has the transmission axis in the vertical direction?
(b) What is Brewster's angle for this case?
(c) What is the index of refraction of the material reflecting the light?
