Electromagnetic
waves can only carry a certain number of basic integer of energy.
Einstein's light quantum in 1905, said that the light waves have a
particle nature of the independent existence of these particles called
photons (quanta, photons), referred to as photons, whose energy is the
basic number of quantized electromagnetic waves, frequency, the greater
the higher the photon energy , and the intensity of electromagnetic
waves is proportional to the number of photons.
