An atom absorbs a photon of wavelength 500 nm and emits another photon of wavelength 600 nm. The net energy absorbed by the atom in this process is n × 10-4 eV. The value of n is____.
[Assume the atom to be stationary during the absorption and emission process]
(Take h = 6.6 x 10-34 js and c = 3 x 108 m/s)
