Quantum Physics(ionization Energy)

  1. Nov 27, 2004 #1
    I need help to do my assignment here,
    :confused: the ionization energy of a hydrogen atom is 13.6 eV.would the absorption of light of frequency 7.00x10^15 Hz cause a hydrogen atom to be ionized?
    :confused: calculate the wavelengths of all the radiations in Lyman series in the hydrogen spectrum.

    please help me answer this because I really dont know much about physics. :cry:

    The first question convert the frequency to energy using [tex] E = h\nu [/tex]. Is it larger than 13.6 eV????

    The Lyman series is the Rydberg series [tex] \frac{1}{\lambda} = R_{h}(\frac{1}{1^{2}} - \frac{1}{n^{2}}) [/tex], [tex] n > 1 [/tex] and [tex] R_{h} [/tex] is the Rydberg constant

    Look here for a link http://en.wikipedia.org/wiki/Rydberg_formula
