Question

Frequency of the series limit of Balmer series of hydrogen atom in terms of Rydberg constant $R$ and velocity of light $c$ is

$\frac{4}{Rc}$

$4\,Rc$

$Rc$

$\frac{Rc}{4}$

Answer

$\frac{Rc}{4}$

Explanation

Solution

Using, $\frac{1}{\lambda} = R \left[ \frac{1}{n_1{^2}} - \frac{1}{n_2{^2}} \right]$ where $n_1$ = 2 and $n_2 = \infty \, \therefore \, \frac{1}{\lambda} = \frac{R}{4}$
Then, $f = \frac{C}{\lambda} = \frac{RC}{4}$
