Planck’s Quantum of LightEnergy emission or absorption for an radiator atfrequency ν can only be in units, or quanta, of hν,2hν, 3hν .. <strong>and</strong> not values in between.Classically, there is no restriction on the amplitude ofthe EM waves <strong>and</strong> energy exchange can be in anyamount, for any ν.The functional form of the Planck distribution makesit increasingly difficult to emit or absorb light at highfrequency because of the very large quanta.33
