Homework Statement
The description of the potential distribution is given in the attached image.
The particle arrives from the left with E>V0.
write the solutions to the S.E in regions x<o and x between o and a
Homework Equations
I believe psi(x)= e^ikx+Re^-ikx in x<0
and psi(x)=Ae^iqx+Be^-iqx for x b/w o and a.
The Attempt at a Solution
My question is, since there is complete reflection occurring at x=a, can A=B in region x b/w 0 and a? If so, there will be destructive interference in the region, giving R=1, which is what we are asked to prove in the question. Is this approach of equating coefficients of wave traveling in +-x directions in this region applicable?
