The electrons in hydrogen gas absorb energy and travel to higher energy levels when the gas is excited, which is typically done by an electric discharge. These electrons produce a series of spectral lines as they decay back to lower states, emitting light at particular wavelengths. Based on the principal quantum numbers involved in the transitions, these lines are grouped into several series: the Brackett series (to n=4), the Pfund series (to n=5), the Balmer series (to n=2), the Paschen series (to n=3), the Lyman series (transitions to n=1). The most noticeable line in the visible wavelength range of the Balmer series appears at 656 nm, which is the transition from n=3 to n=2. The Rydberg formula, which represents the fixed energy differences between the quantised states of the atom, can be used to calculate the wavelengths of these spectral lines. Understanding the hydrogen spectrum is vital to the development of quantum mechanics and is still used in spectroscopy and astronomy to find hydrogen in far-off celestial objects.\n
