1. The problem statement, all variables and given/known data Unpolarized light of intensity Io passed through a Polaroid sheet with its polarizing axis at the 12 o'clock position and then through a second with its polarizing axis at the 1 o'clock position. What is the intensity of the emerging light? 2. Relevant equations I= I0 *0.5*cos2(30) 3. The attempt at a solution Now i know the solution i just want a break down of the question. Why is it that when a unpolarized light passed through a polaroid, it loses 1/2 its intensity? Also where would the 30 degrees come from? Also is it possible to draw this question out?
