Homework Help: 3d box

  1. Sep 7, 2005 #1
    howdy all,
    i need some answers if possible
    suppose i have a particle mass m, confinded in a 3d box sides L,2L,2L
    what would be the energy eigenvalues of this particle
    i presumed it to be:

    where hcross is h/2*pi
    w is omega
    and A is the 'amplitude' of the wavefunction.
    can someone confirm this or tell what it may actually be

    Your answer is not correct, the correct answer should be.
    [tex] \frac{h^2}{8m}(\frac{n_1^2}{L^2}+\frac{n_2^2}{4L^2}+\frac{n_3^2}{4L^2})[/tex],
    [tex]n_1=1,2....., n_2, n_3[/tex] are the same.
