If the series limit frequency of the Lyman series is $V_{L},$ then the series limit frequency of the Pfund series is:

Options:

Answer:

Solution:

$\Rightarrow V_{2} = R C Z^{2} (\frac{1}{1^{2}} - \frac{1}{\infty^{2}})$

$V^{2} = R C Z^{2}$

Series limit frequency of the Pfund series,

$V_{p} = R C Z^{2} (\frac{1}{5^{2}} - \frac{1}{\infty^{2}})$

$V_{p} = \frac{V_{L}}{25}$
