An atom absorbs a photon of wavelength $500nm$ and emits another photon of wavelength $600nm$. The net energy absorbed by the atom in this process is $n\times 10^{-4}eV$. The value of$n$is [Assume the atom to be stationary during the absorption and emission process] (Take $h=6.6\times 10^{-34}\mathrm{J}\text{s}$ and c=3×108 m s-1 ).
