If the electron in hydrogen atom jumps from the third orbit to second orbit, the wavelength of the emitted radiation is given by

Options:

Answer:

Solution:

$\frac{1}{λ} = R [\frac{1}{n_{1}^{2}} - \frac{1}{n_{2}^{2}}]$
$= R [\frac{1}{2^{2}} - \frac{1}{3^{2}}]$
$\frac{1}{λ} = \frac{5 R}{36}$
So $λ = \frac{36}{5 R}$
