Suppose that you have a laser that emits vertically polarized light but that you would like horizontally polarized light instead and you can’t touch the laser. You do, however, have several polarizers which absorb very little light along the polarization axis. In order to get the brightest possible beam of horizontally polarized light, you should (A)use a single polarizer, aligned horizontally
Suppose that you have a laser that emits vertically polarized light but that you would like
horizontally polarized light instead and you can’t touch the laser. You do, however, have
several polarizers which absorb very little light along the polarization axis. In order to
get the brightest possible beam of horizontally polarized light, you should
(A)use a single polarizer, aligned horizontally
(B) use two polarizers, aligned at 45 degrees and9 0 degrees from the vertical, respectively
(C) use as many polarizers as you can, with each one rotated a bit more towards horizontal than the previous one
(D) it is impossible to change vertically polarized light to horizontally polarized light because the original laser light has no horizontal component
