Homework Help: Polarization Problem

  1. Mar 28, 2010 #1
    1. The problem statement, all variables and given/known data

    Two polarizers are oriented at 62° to one another. Light polarized at a 31° angle to each polarizer passes through both. What reduction in intensity takes place?
    ___.%

    2. Relevant equations
    I=IoCos^2((-))


    3. The attempt at a solution
    Tried suing the above equation, and got 16%. I don't know how to deal with the fact that light that did not go through the first polarizer is hitting the second one> Please help. Thank you
