Question 439: Atoms & Nuclei

Question

Frequency of the series limit of Balmer series of hydrogen atom of Rydberg's constant ' $R$ ' and velocity of light ' $C$ ' is

Accepted Answer

Wavelength of Balmer series is given as,
$\frac{1}{\lambda}=\mathrm{R}\left(\frac{1}{\mathrm{n}^2}-\frac{1}{\mathrm{~m}^2}ight)$ where $\mathrm{n}=2$
For series limit, $m=\infty$
$$	herefore \quad \frac{1}{\lambda}=\mathrm{R}\left(\frac{1}{4}-\frac{1}{\infty}ight)=\mathrm{R}\left(\frac{1}{4}ight)$$
Now, $
u=\frac{\mathrm{C}}{\lambda}$
$$	herefore \quad 
u=\frac{R C}{4}$$

Answer

$\frac{\mathrm{RC}}{4}$

Answer
