The first excited state of the hydrogen atom is separated from the ground state by 10.2 eV.
(a) At what wavelength does this occur and what is the energy difference in kJ mol-1 between the ground and excited states? Show your working in each case.
(b) If the degeneracy of the ground state and the excited state is 1, calculate N* / N0 at 2,000 K and 8,000 K.

I barely understand this
