By quantum theory of radiation, the energy change
E between energy levels is proportional to the frequency of electromagnetic radiation
f and is given by the quantion below
E =hf =hc/λ
where
h is the Planck's constant,
c is the speed of light and λ is the wavelength of the radiation. Now, energy change by transition from
E2 to E1 is given by
E = E2 – E1
E2 – E1 = hc/λ
λ = hc/ E2 – E1
Hence, option c is correct.
