Homework Help: Find the energy of oscillator

  1. Feb 26, 2008 #1
    [SOLVED] Find the energy of oscillator

    1. The problem statement, all variables and given/known data
    The Probability density for the states of a harmonic oscillator is shown in the figure. Find the energy of the oscillator in this state if the ground state energy is 2 [eV].

    2. Relevant equations

    3. The attempt at a solution
    n=5 then E_5=5^2*2 eV=50 eV

    This looks wrong to me. The spacing of the energy levels of the harmonic oscillator doesn't go as n-squared, rather it goes as n. I think. Also, the sketch as shown appears to me to be the 9th level, not the 5th. (Try drawing out the first three or four levels to see how it goes.) So I would put this state at 18 eV.
