Every photon has varying degrees of vertical and horizontal
polarization. When you use a polarizing filter, all it does is filter
out the amount of polarization in a photon that is at right angles to
it. If you have a photon with 45 degress of polarization and an
amplitude of 1.414, its amplitude is reduced to 1 as it loses one or the
other leg of polarization to become oriented at either 90 degress or 0
degrees. Imagine it as a vector equation with a 1/1/2^1/2 triangle.
