So imangine a potential well that looks like this: --_--(adsbygoogle = window.adsbygoogle || []).push({});

where the 1st and the third line have a potential U and the 2nd line has U=0.

A wavefunction is coming from the left with E>U.

When the wave function hits the first potential change(where the ΔU = negative), does some of the wavefunction get reflected back? In other words, can a wavefunction that faces a negative change in potential get reflected back?

(and if so, can a wavefunction that faces no change in potential get reflected? I feel like if a wavefunction has a chance getting reflected off a negative potential, then it would have a higher chance getting reflected off no change in potential... but this does not seem right)
