I'd like to test my understanding of polarization, concept new to me. I except that the answer to my following question is "no", but I'm not sure and I don't know why it would be so. If I see a circularly (left of right, it doesn't matter) polarized EM wave going to my eyes and I put a polaroid in front of my eyes such that it polarizes linearly the light. Will the EM wave getting on my retina be a continuous wave? I'd think that no since the polaroid would absorb most of the light and let only pass the wave when the electric and magnetic fields have a very particular direction. So only a small part of the incoming wave would pass through the polaroid, making a discontinuous wave. Is my reasoning erroneous? I guess that yes, but I need an explanation. In other words, would my retina be constantly receiving some EM wave? I think that most of the time, no. Am I right?
