quantum mechanics questions
mark_alec:
I don't know how to prove it, but I know that you have to take as given.

Hmm perhaps it's because the integrand is complex at all times except when
Anyway thanks mark
QuantumJG:
Ok I have a quantum mechanics question and I thought here is probably the best place to ask it.
Anyway I have a proton in a 1-D infinite potential well and the wavefunction for it is:
One part of the question asked me what is the quantum number n, i.e. if:
I found n to be 2 (i.e. the proton is in it's first excited state), by shifting the second equation by to the left.
Another part of this question is to prove that this wavefunction is a solution to the time independent Shrodinger equation. Is this just another way of asking you to show the second derivative of is simply a constant times .
/0:
I guess you could show by differentiation, but you might as well just solve the time-independent schrodinger equation anyway. It wouldn't be a long derivation and it's probably in your book
QuantumJG:
Thanks.
How is your exam timetable? Mine is pretty good quantum & special on the 9th, thermal and classical on the 11th, Real Analysis on the 17th and Introductory personal finance on the 18th.
This year I have really learnt that I love physics (definately more than maths), but I still enjoy maths. You are lucky to do PDE's next semester I have to wait until next year.
