In a hydrogen like atom, when an electron jumps from the M - shell to the L - shell, the wavelength of emitted radiation is $\displaystyle \lambda$. If an electron jumps from N -shell to the L-shell, the wavelength of emitted radiation will be:
Official answer
(3)
$\displaystyle \frac{20}{27} \lambda$
