 I'm not entirely sure as to why they wouldn't since the only thing we really changed between the two systems is that V is now infinite. Therefore, the chance of a particle escaping the well is non-existent making R=1. Unless, of course, if the walls become transparent. I'm not entirely sure as to why they wouldn't since the only thing we really changed between the two systems is that V is now infinite.

 +That's a very good question... the wave function has to be zero outside the infinite square well, and the slope of the sine function is definitely not zero at the well walls; the transmission coefficient could never be greater than zero for an infinite square well, suggested by intuition as well as eqns [2.169] and [2.171]. Griffiths, on pg 71. eqn [2.121], states that <math>\frac{d \psi}{d x}</math> must be continuous //except// at points where potential is infinite, such as the delta function or the wall of the infinite square well.

 This wiki keeps boot'en me off when i go to save what i have edited. is there some limited time frame to editing are is this a common problem, seems to be a new one for me.It happens for creating lecture notes as well, frustrating!  This wiki keeps boot'en me off when i go to save what i have edited. is there some limited time frame to editing are is this a common problem, seems to be a new one for me.It happens for creating lecture notes as well, frustrating!

 +===Yuichi=== You have 15 minutes of inaction.  Then if someone else wants to edit the same wiki, s/he will have a precedence.  but as long as you are typing, you should be able to keep your edit.  If you are losing the edit even if you are not leaving the edit for more than 15 minutes, let me know.  I will check with the systems person.
