The Lyman Series

The energies in electron-Volts for the first several levels of the hydrogen atom are given in the following table.

n Energy (eV)
1 0.00
2 10.20
3 12.09
4 12.75
5 13.06

The energy of a transition is the difference in energies for the initial and final states. What is the range of wavelengths corresponding to the possible transitions in the Lyman series and in what part of the spectrum do they come?
