What is the width of a square well if its ground-state energy is 2.50 eV?

[QUOTE="JR_R, post: 5457351, member: 592330"] Oh man, this was one of my homework problems (assigned on Monday) too. You've got [U[SUB]0[/SUB]=6E[SUB](1−IDW)[/SUB]]. "IDW" I'm pretty sure means Infinite-Depth Well. This is a finite-depth well so you cannot use infinite-depth equations, but this provided equation gives you a way to apply IDW equations to the FDW. In practical terms - what they should have included in the problem - is that we can treat [U[SUB]0[/SUB]=6E[SUB](1−IDW)[/SUB]] as [U[SUB]0[/SUB]=6E[SUB]∞[/SUB]]. This is where I don't know where to go. So I sacrificed my own problem to the "give up" button, took my own answer, divided it by my U[SUB]0[/SUB], multiplied it by yours and then put it into the IDW equation. What I got was L = 0.3064 nm. Maybe that will work. I still have no idea why they thought this was a good problem. I will be writing complaints and talking to my professor. [/QUOTE]
