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?
