Question

What is Rydberg's constant? what is its value?

Answer 1

For the calculation of wavelength of spectral lines Rydberg gave a formula and use a constant called Rydberg's constant.

Formula$\to \frac{1}{\lambda }=R{Z}^2(\frac{1}{n_2^2}-\frac{1}{n_1^2})$

where

$\lambda =$ wavelength

$R=$ Rydberg's constant

$Z=$ atomic number of atom

$n_1\&n_2=$ Integers

The value of Rydberg's constant is $1.0973\times {10}^7{m}^{-1}$
