Question

The solar glare of sunlight bouncing off water or snow can be a real problem for drivers. The reflecting sunlight is horizontally polarized, meaning that the light waves oscillate at an angle of 90º to a normal line drawn perpendicular to the Earth. At what angle relative to this normal line should sunglasses be polarized if they are to be effective against solar glare? (A) 0º (B) 30º (C) 45º (D) 60º (E) 90º The solar glare of sunlight bouncing off water or snow can be a real problem for drivers.
