Hydrogen spectral series

Electron transitions and their resulting wavelengths for hydrogen. Energy levels are not to scale.
energy level diagram of electrons in hydrogen atom
Lyman series of hydrogen atom spectral lines in the ultraviolet

The emission spectrum of atomic hydrogen is divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels in the atom. The classification of the series by the Rydberg formula was important in the development of quantum mechanics. The spectral series are important in astronomical spectroscopy for detecting the presence of hydrogen and calculating red shifts.
