How exactly do certain types of glass filter out light within specific frequencies/wavelengths?
I'm wondering because I read somewhere that certain types of windows filter out certain parts of the electromagnetic spectrum. I've heard about polarization of light, but don't understand how this would apply here or even work in type of glass used in windows.
So in other words, I'm asking: what happens to the light waves as they pass through different types of glass, besides simply being refracted and reflected? How can certain portions of the spectrum just be removed? In case there are multiple methods/effects, please either elaborate or enumerate.
