Polarizing Two Filters

Polarizing Two Filters

i need help understanding what a polarized filter is...?

how do they work? do they work for longidtudinal waves or transverse waves? please help me visualize them!!! when two poalrized filters are put at right angles what happens?
my teacher sad it is a peace of plastic or glass that have microscopic lines. only parallel wave go through thme, not perpendicular wave...they turn black with two sets of them perpendicular to each other. But then at the end of class he said polarized filters only work for transverse waves. WHAT?

your just getting confused in his term longitudinal waves... just think of it how u did before he or she said that.
