The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to electrons making...

Emission can occur at any frequency at which absorption can occur, and this allows the absorption lines to be determined from an emission spectrum. The...

The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed...
