Homework Help: Wave function (schrodinger equation)

  1. Mar 30, 2014 #1
    1. The problem statement, all variables and given/known data
    Sketch the wave function ψ(x) corresponding to a particle with energy E in the potential well shown below. Show correctly relative values of amplitude and wavelength in different regions.


    2. Relevant equations

    3. The attempt at a solution
    I guess I was a bit confused how to get started with this.. there's nothing like this in my notes so I'm kinda guessing. but from the picture I can see E is a staight line (constant) and it only oscillates when E>V0 otherwise it is decaying (e^x or something). So i graphed rough sketch of the wave function..am I doing anything that is wrong?

    Your understanding of what to do is correct. Of course in the region when the energy of the particle is greater than the potential: one measures a free particle like solution with varying frequencies.

    There are two questionable parts for me in your solution. There isn't a decay before the first measurable wall and the second well oscillates too slowly being only 2 units higher than the first.
