An excited hydrogen atom returns to the ground state. The wavelength of emitted photo is $λ$ . The principal quantum number of the excited state will be

Options:

Answer:

Solution:

$\frac{1}{λ} = R [\frac{1}{n_{1}^{2}} - \frac{1}{n_{2}^{2}}]$
$= R [\frac{1}{1^{2}} - \frac{1}{n^{2}}]$
$n = {[\frac{λ R}{λ R - 1}]}^{1 / 2}$
