Homework Help: Angle of strongest polarization

  1. Apr 7, 2009 #1
    1. The problem statement, all variables and given/known data
    At what angle above the horizon is the Sun when light reflecting off a smooth lake is
    polarized most strongly?

    2. Relevant equations

    dsin(θ) = mλ

    I = E^2

    3. The attempt at a solution

    I think that the polarization is strongest when the angle between the light and the water is closest to or at 90 degrees, which would occur at noon. I dont have a good explanation for this, though. Can anyone help?
