Problem

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 \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}

J s and

c = 3 \times 10^8

s^{-1}
