Definition of Rydberg formula in English:
Rydberg formula
noun
(also Rydberg's formula)
Physics An equation giving the wave numbers of the spectral lines of hydrogen or hydrogen-like atoms, especially of a hypothetical atom having a nucleus of infinite mass.
The Rydberg formula for a hydrogen-like atom is 1/λ = RZ 2(1/n 2 − 1/m 2), where λ is the wavelength of the light, R is the Rydberg constant, Z is the atomic number of the atom, and n and m are whole numbers, with m > n.
Origin
Late 19th century; earliest use found in Astrophysical Journal.
