I Dont understand how light polarized along a certain axis in a prepared state can then pass through a second polarizer that is at an angle to the first. The experiment I’m trying to understand starts with unpolarized light which then passes through a first filter which vertically polarizes the light, such that all light that is passed through is vertically polarized. Then the light passes through a second 45 degree polarizer. My understanding is that 50% of the light will pass through. But why is that when none of the light was originally in the 45 degree plane? It is not that the light is oscillating at 45 degrees and has a component that oscillates vertically and another component that oscillates horizontally. It is only the measuring device that is in a 45 degree angle. The light was prepared in a vertical direction.
