Rydberg's formula for the wave number of a hydrogen spectral line is

Question

Accepted Answer

D. $\bar{
u} = R\left(\dfrac{1}{n_1^2} - \dfrac{1}{n_2^2}ight)$

$\bar{
u} = R_H\left(\dfrac{1}{n_1^2} - \dfrac{1}{n_2^2}ight)$, $n_2 > n_1$.
For hydrogen, $R_H = 1.097 	imes 10^7\,m^{-1}$.

Answer

$\bar{
u} = R(n_1^2 - n_2^2)$

Answer

$\bar{
u} = R\left(\dfrac{1}{n_1} - \dfrac{1}{n_2}ight)$

Answer

$\bar{
u} = R\left(\dfrac{n_2}{n_1}ight)$
