Students have asked these similar questions
(a) What is the wavelength of light for the least energetic photon emitted in the Balmer series of the hydrogen atom spectrum lines? (b) What is the wavelength of the series limit?
If a hydrogen atom in the ground state absorbs a 93.7 nm photon, corresponding to a
transition line in the Lyman series, how does this affect the atom's energy and size?
How much energy is needed to ionize the atom when it is in this excited state? Give
your answers in absolute units, and relative to the ground state.
(the Lyman series is a hydrogen spectral series of transitions and resulting ultraviolet emission lines of
the hydrogen atom as an electron goes from n ≥ 2 to n = 1 (where n is the principal quantum number),
the lowest energy level of the electron.)
