A beam of particles travels in the z-direction. These particles have two orthogonal states of linear polarization, denoted by |xgt; and |ygt;. The...

I am asked to find the conditions imposed on the variables based on the requirement that the wave function be normalized along with expanding the vector |phi (0)> in the |x> and |y> polarization basis.I am unsure where too begin as we have not yet covered the polarization basis. Could it be that perhaps a solution could be found within another topic?
