A particular hydrogen like ion emits radiation of frequency $2.92 \times 10^{15} Hz$ when it makes transition from $n = 3$ to $n = 1$ . The frequency in $Hz$ of radiation emitted in transition from $n = 2$ to $n = 1$ will be:

Options:

Answer:

Solution:

As we know,

$ν \propto [\frac{1}{n_{1}^{2}} - \frac{1}{n_{2}^{2}}]$

$\frac{2.92 \times 10^{15}}{ν} = \frac{[\frac{1}{1} - \frac{1}{9}]}{[\frac{1}{1} - \frac{1}{4}]}$

$ν = 2.92 \times 10^{15} \times \frac{3}{4} \times \frac{9}{8}$

$ν = 2.46 \times 10^{15} Hz$
