Help on double slit with different polarizations

  1. Jan 3, 2008 #1
    1. The problem statement, all variables and given/known data
    I am taking Young's Double slit expariment setup, however now I am changing the polarization. Below is the typical intensity when both slits have the same polarization, what I need to know is how the intensity graph changes when there is a difference of 90º and 180º in the polarization between the two slits.

    I have been trying to find any explination of this without luck, nor have I found what equation I need. I think I may need the equation I(θ)=Io(Sin/u)^2 * Cos[v]^2 because it has two angle dependences, but even if I do I am not sure what values go where.

    Any help is greatly appreciated.

    At a difference of 90 degrees in polarization, there will be no interference.
    180 degrees is the same as 0 degrees for polarization.
