Homework Help: Electron In An Infinite Potential Well

  1. Nov 22, 2008 #1
    1. The problem statement, all variables and given/known data

    An electron is in a Infinite potential well (1-dimensional box with infinite wall boundary conditions) at the second energy level. The width of the box is L. What is the electron density n(x) as a function of the position x?

    2. Relevant equations
    time-independent Schrödinger equation:
    general solution:

    3. The attempt at a solution

    From http://en.wikipedia.org/wiki/Particle_in_a_box#1-dimensional_box"

    I'm not sure what the next step is. I'm confused with the wording "electron density n(x)". Does this mean probability (i.e. [itex]\|\psi_n(x)\|^2[/itex])?

    Yes, it does.

    So does that mean[itex]n(x)=\|\psi_n(x)\|^2[/itex] ?
