A particular hydrogen like ion emits radiation of frequency $\displaystyle 2.92 \times 10^{15} \mathrm{~Hz}$ when it makes transition from $\displaystyle \mathrm{n}=3$ to $\displaystyle \mathrm{n}=1$. The frequency in Hz of radiation emitted in transition from $\displaystyle \mathrm{n}=2$ to $\displaystyle \mathrm{n}=1$ will be :
Official answer
(4)
$\displaystyle 2.46 \times 10^{15}$
