A photon interacts with a ground state electron in a hydrogen atom and is absorbed. The electron is ejected from the atom and exhibits a de Broglie wavelength of 3.188×10−10 m. Determine the frequency (in hz) of the interacting photon.

  • chemistry -

    frequency * wavelength=speed light

  • chemistry -

    no

  • chemistry -

    the wavelength is for electron, whereas the frequency of photon is needed

  • chemistry -

    First find: E = P^2/2Me + E(first ionization)

    P= h / BroglieWavelength

    E(first ionization)=21.7*10^-19

    Me= 9.1*10^-31

    h= 6.626*10^-34

    Once E is found the find frequency:

    frequency(hz)= E / h
