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 proportional to :

Options:

Answer:

Solution:

$Δ E = h ν$

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

$\approx \frac{2 k}{n ^{3}} \propto \frac{1}{n ^{3}}$
