Homework Help: To what significance is the two different paths of the light?

  1. Nov 14, 2006 #1
    Hey guys,
    I have a problem with a polarization question...
    Consider the experiment H filter ← +45◦/ − 45◦ loop ← V photon. What is the output of
    the H filter? Write down an equation describing this outcome, in terms of the probability amplitudes
    for each step. Note that the +45◦/ − 45◦ loop has two branches!

    Now, I cant get my head around the fact that the result would be 0. A 45/-45 loop would just recombine the polarized like together, thats what a loop does. So therefore the light when reaching the filter would just be V photon, and none would pass through.
    To what signifigance is the two different paths of the light?
    Any opinions is appreciated
