Some energy levels of a molecule are shown in the figure. The ratio of the wavelengths $r = \frac{λ_{1}}{λ_{2}}$ , is given by:

Options:

Answer:

Solution:

The relation between wave length and energy of electron in $n^{t h}$ orbit

$λ_{1} = \frac{- h c}{E}$
$λ_{2} = \frac{- 3 h c}{E}$
$\frac{λ_{1}}{λ_{2}} = \frac{1}{3}$
