Consider wavefunction psi (subscript "nlm") describing the electron in the stationary state for the hydrogen atom with quantum numbers n,l,m and the third component L3 for the orbital angular momentum operator L. What is the expectation value of L3 and of L3^2 for the state described by psi?

2. Relevant equations

3. The attempt at a solution

L = sqrt(l(l+1)*hbar).

And I think L3 is the same as Lz

Lz = m*hbar

but I don't know what stationary state implies in terms of quantum numbers.
