Question

Write equations for Rydberg's const and give its unit

Answer 1

Rydberg constant, (symbol R ∞ or R Η ), fundamental constant of atomic physics that appears in the formulas developed (1890) by the Swedish physicist JohannesRydberg, describing the wavelengths or frequencies of light in various series of related spectral lines.

Answer 2

Rydberg's equation =
1/lambda square = RZ^2[1/square of principal quantum no. in final state - 1/square of principal quantum no. in initial state]..

lambda= wavelength
R= Rydberg's constant
Z=no. of protons in nuleus of element..
constant quantity is unitless..
