Which hydrogen spectral series lies in the visible part of the spectrum?
The hydrogen spectral series that lies in the visible part of the spectrum is the Balmer series.12
Discovered by the Swiss mathematician Johann Balmer in 1885, this series consists of spectral lines produced when an electron in a hydrogen atom transitions from higher energy states to the specific state where the principal quantum number . The Bohr model, proposed by the Danish physicist Niels Bohr in 1913, successfully accounted for these discrete wavelengths by limiting electrons to specific circular orbits and defining radiation as the energy released during transitions between these states.123
Other hydrogen spectral series, such as the Lyman series, fall within the ultraviolet region, while the Paschen, Brackett, and Pfund series are located in the infrared region of the spectrum.2
