Reflected light from a polarizer

Hi Folks,

I have a general question. What happens to unpolarized light once it's reflected from a polarizer?

My best guess is that it's polarized with opposite parity relative to the transmitted light with intensity varying as a function of angle of incidence.

I think my answer applies to any polarizer (linear or circular). If you have a reference that addresses effects upon reflection from a polarizer, I'd be glad to read more. Thanks.

There are different kinds of polarizers: for example, a Glan-Thomspon prism transmits the orthogonal states in different directions. Polaroid (IIRC) absorbs one component.

I'm sorry, I did not mention I'm assuming a sheet polarizer. However, I guess it doesn't matter too much. I'm just curious about how different the reflected component would be from the transmitted counterpart (in a general sense).
