Hi. I would like to know which variables in the wave function are constant (in this local context) and which are not. The wave number for instance varies in the article I was reading (WKB approximation). Why is this so? What other variable in the wavefunction can vary?(adsbygoogle = window.adsbygoogle || []).push({});

Please help me as I am young and new to this...
