An atom absorbs a photon of wavelength$500 \mathrm{nm}$and emits another photon of wavelength$600 \mathrm{nm}$. The net energy absorbed by the atom in this process is$n\times {10}^{-4}\mathrm{eV}$. The value of$n$is [Assume the atom to be stationary during the absorption and emission process] (Take$h=6.6\times {10}^{-34}\mathrm{J} \mathrm{s}$$$and$c=3\times {10}^8 \mathrm{m} {\mathrm{s}}^{-1}$).
