Hydrogen Spectrum & Spectral Series

Which one of the following spectral series of hydrogen atom lies in ultraviolet region?

Show answer and solution

Answer: (a)

Lyman series ends on $n = 1$ ; its photons have energies $10.2$ to $13.6$ eV, i.e. wavelengths $91$ to $122$ nm.
Paschen, Brackett and Pfund lie in the infrared.
So the answer is (a) Lyman.
