Unless it's a typo (very possible with this prof), the problem asks for L_y . I looked through griffith's ch.4, and the closest I could come up with is L^2*ψ = \hbar^2*l(l+1)ψ, which worries me, as that would introduceL_x^2 and L_z^2 . My problem with the given information stands though, even...

Homework Statement I have two separate problems with the same issue; I don't grasp what information the equation of state is giving me. a. A system with l=1 is in the state ψ> = (1/√2) 1> - (1/2) 0> + (1/2) -1> Find Ly. b. A spin 1/2 is in the state ψ> = (1+i)/3 +> + (1/√3) ->...
