Ah thank you. Now that brings up another question for the same problem but now E>Vo. The wave equations go to: Aexp(ikx) + Bexp(-ikx) when x < 0. k=sqrt(2mE)/hbar Cexp(ilx) + Dexp(-ilx) when x > 0. l=sqrt(2m(E-Vo))/hbar Now in this case why does D=0.

Homework Statement I'm working through a step potential and I am confused as to why one of the coefficients doesn't go to zero. V(x) = 0 when x < 0; V(x) = V_not when x > 0; a. Calculate reflection coefficient when E < V_not I can solve the reflection part, it is a step towards it...
