Homework Help: Frequency question

  1. Sep 1, 2005 #1
    there's 2 frequency formulas:
    1. f=e/2pi(4pi*epsilon*mr^3)^(1/2)
    2. 1/namda=-E/ch[1/(nf^2)-1/(ni^2)]
    are those the same thing?

    NO!

    the first, if you follow the words thru the derivation,
    is the frequency that the electron orbits the center.

    the second is the frequency of the light emitted
    during a CHANGE from one orbit to another.

    (If the n's are small integers, we should expect that
    the two are roughly the same order-of-magnitude,
    so the light comes from a resonance in the changing atom)
