Saha equationA formula, derived by the Indian astrophysicist Meghnad Saha (1894–1956) in 1920, that gives the fraction of atoms in each different excited state in a gas in thermal equilibrium at some specified temperature and total density. This in turn predicts the strength of spectral lines. Related category• SPECTRA AND SPECTROSCOPYAlso on this site: Encyclopedia of Alternative Energy & Sustainable Living Encyclopedia of History |
