Homework Help: Barrier potential representation

  1. May 28, 2010 #1
    Having trouble drawing the wave representations for this diagram.

    [PLAIN]http://img156.imageshack.us/img156/94/diag.png [Broken]

    I'm not sure what the incident and reflected waves should look like.

    The question is asking to draw the waves in each region. I understand how to calculate the waves just not how to represent them.

    Any help appreciated thanks.

    EDIT: I also understand that the wavelength must be smaller in the middle. What I'm unsure of is where exactly to draw the reflected waves.

    Reflections occur when there's a change in the potential, so there are two places a reflection can occur.

    Yes but how do I depict these reflections? Are they above or below the waves at E ?

    They're at E. They have the same total energy as the incident wave.
