The Energy of a Photon

For electromagnetic radiation the energy of a photon is the frequency multiplied by the Planck constant h.The Planck constant is h = 6.63 × 10^-34 J s.For radiation of frequency f, energy can only be transferred in whole packets (photons) of energy hf.This means that some energy values are impossible i.e. the energy transferred must be a whole number multiple of hf.This system of minimum sized steps is called quantisation.The energy of a photon is given by:E = h fwhere E is the energy of a single photonf is the frequencyh is the Planck constant
