Obtaining expression for the angular momentum operator
How do you obtain an expression for L^2 (tbe angular momentum operator) in spherical polar from the expression for angular momentum L = R x P?
Measuring Angular momentum A particle is in the state with wave function shi = 1/sqrt(2)[Y11 + Y1-1] (a) What value is obtained if L^2 is measured? (b) Does the particle have a definite value of Lz? (c) What are the probabilities of getting results h bar and - h bar and 0 for Lz? Are any other Lz results possible ...continues
Could you please show me how to do the question attached? Don't do the parts that are crossed out in red. Thank you.
Equations of motion for expectation values
Could you please show me how to prove the relations in the MS Word problem attached? The problem is called Equations of motion for expectation values. Thank you.
Could you please show me how to do the problem that I have attached? I just want answers where momentum and energy commute and therefore have both definite values. Thank you.
Total angular momentum operator
Could you please explain the two short questions I have attached? Thank you.
Sketches of angular momentum eigenfunctions
I have attached part of a problem. Could you please do part d, which involves sketching of three ang. momentum wavefunctions in the x - z plane with l=1 and m=-1, m=0 and m=1. Could you also please explain how you drew these graphs? Thank you.

Photoelectric Effect: Energy of photoelectrons emitted.
Light from a laser hits the surface of cesium. With a minimum photon energy of 2.14eV being required to remove photons. When the surface of cesium is illuminated with this light photoelectrons are emitted with a max kinetic energy of 0.76eV. Assuming that the Planck constant is 4.14x10^-15 eV Hz-1. What would be the energy of ...continues
