212 A photon polarization state for a photon propagating in

2.12. A photon polarization state for a photon propagating in the z direction is given by 2 2 3

Solution

As mentioned before:

All you got to do is to find the magnitude of the coefficient properly chosen.

a) For the porbability of passing through a polarizer along y axis, you take the magnitude of the coefficient of the |y> component. i.e: 1/3 or 33% probable.
