Find bugs, get paid.
If you find typos and errors in any of my materials uploaded, let me know, and you will get paid ... with the currency of a small bonus to the homework score of the week. If you find some strange things, you report them to me and then I realize that they are my mistakes, that will also count as your finding the bug.

Hi Sam,
ReplyDeleteOne question about 1a on this week's homework:
Kelsey and I took two different approaches to solving for hbar*omega. She used the virial theorem to equate T and V in the hamiltonian, and I did not, instead I used the values for V shown in Griffiths treatment of the SHH (V = m(w^2)(x^2)/2).
This gives me a quadratic in w, which gives two real frequencies, whereas she gets one from her treatment. Obviously the ground state oscillation should only have one frequency, so I am clearly doing something wrong, but I was curious why and what?
Isaac, I just checked this one. As discussed during the OH, the solution is obtained either way. Your approach was just as good as the other approach for the ground state, but cannot be applied to excited states.
