### Wave Functions

From what I understand, in the magnetic quantum number (ml), for l=1, ml= -1,0,+1. Because the subscript goes px, py, pz, py is the middle term, just as 0 is the middle term. Thus, py=0. I believe px and pz would be interchangeable for -1 and +1. Hope this helped!

Can De Broglie's Wave Equation work for any particle with momentum?

The De Broglie equation works for any particle that has a mass when the momentum is 0. Since photons never have 0 momentum, you can't use this equation for such particles.

px, py, and pz correlate to the ml=-1,0,+1. px and pz can be either -1 or +1, but pt must be the middle number for the list of ml values is what I understood.
