I am having trouble with an exercise from Griffiths "Introduction to Quantum Mechanics". The exercise is this:(adsbygoogle = window.adsbygoogle || []).push({});

"Suppose you add a constant [tex]V_0[/tex] to the potential energy. Inclassicalmechanics this doesn't change anything, but how aboutquantummechanics? Show that the wave function picks up a time-dependent phase factor: [tex]exp(-iV_0t/\bar{h})[/tex]. What effect does this have on the expectation value of a dynamical variable?"

This is an exercise from the first chapter - the ScrÃ¶dinger equation has only been introduced briefly and he hasn't really talked about potential energy yet. How am I supposed to do this with the limited knowledge I have?
