I'm trying to analyze the reflection of a plane wave of energy E on the box potential where(adsbygoogle = window.adsbygoogle || []).push({});

v(x)= 0 for x<-a

-Vnaught for -a<x<0

infinity for 0<x

and I'm trying to solve the schroedinger eqn. through:

Phi(x) = e^ikx + r(k)*e^-ikx in region 1

A(k)sin(k'x) in region 2

Continuity of phi and phi'/phi at x=-a.

I'm trying to solve for r(k) and A(k), so I've gone and derived all the nastiness, and I get something like r=2ikr'- r'' and A''/A= (-hbar^2/2m)-Vnaught-E

I'm supposed to be able to tell what it means physically that the abs. value of r(k) = 1? I can'tget r(k) to equal one, and I can't find A max. How would I do this??
