Answer:
Rydberg constant, (symbol R∞ or RΗ ), fundamental constant of atomic physics that appears in the formulas developed (1890) by the Swedish physicist Johannes Rydberg, describing the wavelengths or frequencies of light in various series of related spectral lines, most notably those emitted by hydrogen atoms in the Balmer

Answer:
Explanation:
In spectroscopy, the Rydberg constant, symbol for heavy atoms or R_{\text{H}} for hydrogen, named after the Swedish physicist Johannes Rydberg, is a physical constant relating to the electromagnetic spectra of an atom.
Rydberg constant =
10 973 731.6 m-1
he value of Rydberg's constant is 1. 09×106 m−1 if the energy of electron in the second orbit of hydrogen atom is -3.4eV.
