three parts to this one, I can't seem to justify my values, units cancel, but the numbers don't seem right. I think I may have used a wrong equation for part B but I don't know what else to use. Problem: An electron is confined to an infinitely deep potential well of width 0.120 nm. a.)...

I figured it out, my book did not give me this equation for hydrogen-like atoms: 1/lambda = R*Z^2(1/n'^2 - 1/n^2) this gives me 0.97 nm Thanks wikipedia!

I have been having trouble with this Balmer wavelength problem and was hoping I can get a little guidance. The question: Find the balmer wavelength (n=3 --> n=2) emitted from a hydrogen-like Fe atom (z=26) The answer is supposed to be 0.971 nm My attempt: 1/lambda = R(1/n'^2 - 1/n2)...

Awesome, thanks. And okay I gotcha, I will next time. I need to brush up on my trig.

Thank you for your your reassurance and help. And yes it is L' and not a delta L'. I got a bit carried away with deltas I suppose. And wow that last part was very simple, I feel pretty dumb now, I was trying to use a relativistic type equation. So i got L' = 1.22 L . If I am right, that does...

Hello all, I have an exam on Monday and am having trouble with this problem, any help would be greatly appreciated! Q: A straight stick of length L' is at rest in the moving S' frame. The stick appears to have length L in the S frame. The S' frame is moving at a velocity √(2/3) c...
