In a hydrogen like atom, electron makes transition from an energy level with quantum number $n$ to another with quantum number $(n - 1) .$ If $n > > 1,$ the frequency of radiation emitted is (almost) proportional to

Options:

Answer:

Solution:

$Δ E = h v$
$= k [\frac{1}{{(n - 1)}^{2}} - \frac{1}{n^{2}}]$
$= \frac{(k) 2 n}{n^{2} {(n - 1)}^{2}}$
$≃ (\frac{2 k}{n^{3}})$
