Okay, I have a picture of a square wave in an infinite potential box. I need to figure out what the wavefunction is so I can find the expectation value of H. I know how to find the expectation value but I need a psi to be able to do that. I don't know what psi would be for a square wave. I don't...
I don't know the wavefunction for the wave and that's what I need to find. I'm looking for the wavefunction at t=0. I forgot to mention that. I know how to find the solutions in any other situation but the fact that it's a square wave is messing me up.
I've got a square wave between -L/2 to L/2 in an infinite potential well of the same width. I need to find an equation for this square wave. I'm not sure how to do that.
Alright, so here's my problem. I've got a wavefunction between -L/2 and L/2 (symmetric around 0). It's a square wave and it is in an infinite potential well. That's all I know about it. I need to find the wavefunction of it. I was thinking of doing a Fourier sine/cosine series but I'm stuck...
