A hydrogen atom makes a transition from $\displaystyle \mathrm{n}=5$ to $\displaystyle \mathrm{n}=1$ orbit. The wavelength of photon emitted is $\displaystyle \lambda$. The wavelength of photon emitted when it makes a transition from $\displaystyle \mathrm{n}=5$ to $\displaystyle \mathrm{n}=2$ orbit is
Official answer
(D)
$\displaystyle \frac{32}{7} \lambda$
