Here's a slightly more intuitive way of thinking about it. A filter doesn't strictly remove light -- what it really does is add a light wave which destructively interferes with part of the incoming ...

Web2 Linear polarization We say a plane wave is linearly polarized if there is no phase difference between Ex and Ey. We can write linear polarizations as E~ 0 =(Ex,Ey,0) (8) and choose the overall phase so that Ex and Ey are real numbers. If Ey =0 but Ex =/ 0, we have E~ =E 0 xˆei(kz−ωt) (9) with E0 = E~0 just a number now.Then, from Eq.
