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