Homework Help: Schrodinger equation help

  1. Oct 25, 2005 #1
    I'm given the value of a normalized wave function at t=0 (see attachment) and i'm asked to find the wave function at some time t. I have no idea where to even begin, the book has zero examples of anything and I'm just stuck :confused:

    What does your book have to say about the time evolution of a wavefunction? More specifically, have you been told what the time evolution operator is?

    mathlete,

    I can't see yout attachment so I don't know what level you're at, therefore I'm going to give a fairly basic approach. If I have an exact energy state [tex] \psi_E(x) [/tex] that satisfies the time independent Schrodinger equation [tex] H \psi_E = -\frac{\hbar^2}{2m} \frac{d^2\psi_E}{dx^2} + V \psi_E= E \psi_E, [/tex] then how does [tex] \psi_E [/tex] change in time? Hint: use the time dependent Schrodinger equation.
