Homework Help: Bohr model

  1. Dec 13, 2009 #1
    1. The problem statement, all variables and given/known data

    Classical physics applied to the bohr model of the hydrogen atom would predict that light could be emitted continuously, rather than in discrete chunks of energy. Transitions between what kinds of energy levels would come close to the classical viewpoint?

    A. Only levels having small quantum numbers.
    B. Only when at least one of the levels has a very large quantum number.
    C. Only levels of moderate quantum numbers.
    D. There are no such levels.

    3. The attempt at a solution

    Have no idea what it is

    Think of it like this: a blackbody spectrum is what you get when there are a bunch of different energy transitions that could be made.

    A hydrogen atom in the n=2 (princple q#) state has (basically) only one transition with only one possible energy, the Lyman-alpha line. Clearly this one line isn't a nice smooth blackbody spectrum. For a blackbody spectrum, you want a system that isn't constrained to only one or a few transitions, you want something with possible transitions of all different energies.
