In physics, a photon is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves. The concept of the photon was developed by Albert Einstein based on Max Planck's work on blackbody radiation, explaining phenomena like the photoelectric effect. This particle nature of light is part of the wave-particle duality concept.
Light exists as tiny particles which are called
