When an electron jumps from the orbit $n = 2$ to $n = 4$,then wavelength of the radiations absorbed will be ($R$ is Rydberg’s constant)

(d) $\frac{1}{\lambda}$= $R\left\lbrack \frac{1}{n_{1}^{2}} - \frac{1}{n_{2}^{2}} \right\rbrack$
$n_{1}$=2, $n_{2}$=4
$\frac{1}{\lambda} =$ $R\left\lbrack \frac{1}{4} - \frac{1}{16} \right\rbrack$
$= R\left\lbrack \frac{4 - 1}{16} \right\rbrack$ $=$ $\frac{3\ R}{16}$
$\lambda = \frac{16}{3R}$
