What is the expression for the rydberg constant ? Give the meaning of the symbols used .
Answers
Explanation:
In the science of spectroscopy, under physics, Rydberg constant is a physical constant relating to atomic spectra. Denoted by R∞ for heavy atoms and RH for Hydrogen. Rydberg constant was first arose from Rydberg formula as a fitting parameter. Later Neils Bohr has calculated it from fundamental constants.
Rydberg Constant Value
R∞ and electron spin g-factor are the most accurately measured physical constants.
Rydberg Constant Value,R∞ 10973731.568508(65) m-1
Rydberg Constant Value,R∞ 1.097 x 107m-1
Rydberg Constant In Other Units
In atomic physics, this constant is often used and expressed in the form of Rydberg unit of energy. Thus,
Rydberg Constant in Joules 1Ry=2.178 *10-18J
Rydberg Constant in eV 1Ry=13.605693009 eV
