7. A single photon, from an unpolarized source, traveling in thez direction is directed through a series of three polarizers: firsta polarizer with its axis in the x direction, then a polarizer at25 degrees to the x direction, then finally a y polarizer.
a) What is the probability that the photon makes it through thefirst (x) polarizer and what is the photonâ€™s polarization after itcomes through the first polarizer?
b) For a photon that got through the first (x) polarizer, whatis the probability that that photon goes through the next twopolarizers and what is the photonâ€™s polarization after it comesthrough the last polarizer?
c) If the middle (25 degree) polarizer is removed, what is theprobability that the photon gets through both (remaining)polarizers?
