OK... I got this far and I corroborated my answer with a classmate's.
Here's my latest problem... I multiplied out the three matrices using Mathematica and result (the "something" mentioned above in bold) was ridiculously long. I was expecting some of the things to cancel out, but it didn't...
Thanks a lot! So basically, the first step is to figure out each k and solve the equation for psi? I guess that k2 and k3 are the same as k1 and k4, except that I replace "E" with "V-E", right?
That's what I thought I'm supposed to do, but I'm not sure if I'm doing it right. Does that mean that I need to plug it into psi(x) = [(2/L)^(1/2)] [sin(n*pi*x/L)] ? My professor didn't do a very good job of explaining Schrodinger's equation, so I don't have a very thorough understanding of...
I have a wave function problem that I need to figure out... I have a really borderline grade, so it could mean the difference between an 'A' and a 'B' in my graduate Modern Physics class.
Basically, I have to figure out the wave function and the transmission and reflection coefficients. My...
Are there any medical physicists here? I am trying to decide between a career as a medical physicist or as a nuclear medicine physician (I just finished my undergrad in chemistry, so I think I can still go either way). I think I'm more interested in the physics side of things than the medicine...
