Hi, is a linear polarizer acting like an active element that rotates polarization angle or is it just a passive element?
I wonder about this because there is this experiment with three polarizers, where two of them are rotated 90 degree to each other so no light can pass through, and then third polarizer is put between those two with i.e. 45 degrees so that light can pass.
What physical phenomena is behind this?
Best regards.
