determine the end (final) value of n in a hydrogen atom transition, if the electron starts in n=2 and absorbs a photon of light with a frequency of 4.57 x 10^14 Hz.

    E = h*frequency
    Solve for E.
    E = 2.180E-18*(1/4 - 1/x^2)
    Solve for x which is the end orbit for the electron. The 1/4 comes from 1/n^2 - 1/2^2 = 1/4.
    I looked at it quickly; I think x = 3.
