If a more complicated atom has two energy levels for its electrons at (-15) eV and (-30.1) eV, what is the wavelength of the photon (in nm) that is emitted when an electron transitions between these two levels?

  • physics -

    The energy difference between levels is 15.1 eV. Convert that to Ephoton, in Joules.

    Ephoton = 2.42*10^-18 J

    Set that equal to h*c/(wavelength) and solve for the wavelength.

    h is Planck's constant.
    c is the speed of light

    The photon will be in the very far "vacuum" ultraviolet.
