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