Homework Help: Width of Potential Well

  1. May 26, 2005 #1
    hey guys i am kinda stumped on this problem, if anyone can give me a helping hand, it's be much appreciated, thanks!

    An electron is trapped in a one-dimensional infinite potential of width L. As the electron falls from the n=3 to the n=2 eigenstate, it emits a photon with a wavelength of 1649A. How wide is the potential well?
