Light polarised at 45° to the plane of incidence is incident on a smooth dielectric surface at
the Brewster angle. State the polarisation of the reflected beam (relative to the plane of
Brewster Angle -
tan θ = n2/n1
The Attempt at a Solution
I simply don't understand the question. If the light is polarized and incident at the Brewster angle shouldn't there be no reflection as in brewster windows? I can't actually seem to find much material that covers already polarized light and the brewster angle. Is the effect on the light the same as un-polarized light? So does it simply become horizontally polarized and therefore 45° + 90°?
Any help would be appreciated :)
