Homework Help: Quantum mechanics basic question on azimuthal wave function.

  1. May 8, 2014 #1
    1. The problem statement, all variables and given/known data

    Applly conditions to azimuthal wave function for an electron in the hydrogen atom to show that ml, the magnetic quantum number, can take on any integer value.

    See attachment for actual question.

    2. Relevant equations

    I'm pretty stuck, is it something to do with the radial equation? Or separating variables?

    3. The attempt at a solution

    An acceptable wave function can only have a single value for any given angle ##\phi##.

    Yes, because it is continuous with respect to the variable, and its derivate.

    So, would you suggest differentiating the wave function and letting the derivative equal the original wavefunction?

    I tried this and got:

    ml = [itex]\frac{1}{i}[/itex]

    But I don't see how this shows that ml can only take the integer values?
