Homework Help: Exciting an electron in a hydrogen atom.

  1. Oct 13, 2009 #1
    1. The problem statement, all variables and given/known data
    A hydrogen atom in its ground state is illuminated with light having a wavelength of 96.7 nm. can the hydrogen atom's electron be excited to a higher energy state by absorbing one of these photons? If so, determine the state and wavelength of any photon that would be emitted by the atom.

    2. Relevant equations

    3. The attempt at a solution
    =2.0556x10^18 J

    Convert to / by 1.602x10^-19 eV = 12.83eV

    En=-13.6eV/1^2 = -13.6eV

    So I think that the photon energy would have to exceed 13.6eV to excite the electron, so in this case it would not excite it. Is this right?
