Definition of Rydberg constant in English:

Rydberg constant

noun

Physics

A constant, 1.097 x 10⁷ m⁻¹, which appears in the formulae for the wave numbers of lines in atomic spectra and is a function of the rest mass and charge of the electron, the speed of light, and Planck's constant.
〔物理〕里德伯常数
Example sentencesExamples
- Five recent measurements of the frequencies of optical spectral lines in atomic hydrogen and deuterium have improved the accuracy of the Rydberg constant beyond 1 part in 109.
- Our aim is a measurement of the Rydberg constant, directly in frequency units, with an uncertainty of less than 10−10.

Origin

Early 20th century: named after Johannes R. Rydberg (1854–1919), Swedish physicist.
