Question

Angle between polarizer and analyzer in polarizing microscope

Answer 1

Answer:

1. The problem statement, all variables and given/known data Consider a polarizer-analyzer arrangement, as shown (here's a link http://i.imgur.com/APZRJ6J.png ) At what angle is the axis of the analyzer to the axis of the polarizer if, after passing through both sheets, the beam intensity is reduced by 67.6 percent? Answer in units of ◦ 2. Relevant equations I=(1/2)I_o I=I_o*cos^2(∅) 3. The attempt at a solution Since the beam intensity is reduced by 67.7%, I knew I/I_o was .676, so I tried doing ∅=cos( √ .676 .676) but it wasn't right. I'm not sure what I did wrong and whether I'm supposed to use the first equation in this type of problem or not
