If $ν_{1}$ is the frequency of series limit of Lyman series, $ν_{2}$ is the frequency of first line of Lyman series and $ν_{3}$ be the frequency of the series limit of Balmer series. Then

Options:

Answer:

Solution:

$ν_{1} = c R (\frac{1}{1^{2}} - \frac{1}{\infty^{2}}) = c R$
$ν_{2} = c R (\frac{1}{1^{2}} - \frac{1}{2^{2}}) = \frac{3 c R}{4}$
$ν_{3} = c R (\frac{1}{2^{2}} - \infty) = \frac{c R}{4}$
So $ν_{1} - ν_{2} = ν_{3}$
