Both the nucleus and the atom of some element are in their respective first excited states. They get de-excited by emitting photons of wavelengths $\displaystyle \lambda_{\mathrm{N}}, \lambda_{\mathrm{A}}$ respectively. The ratio $\displaystyle \frac{\lambda_{\mathrm{N}}}{\lambda_{\mathrm{A}}}$ is closest to :
Official answer
(1)
$\displaystyle 10^{-6}$
