nouna quantum of electromagnetic radiation; an elementary particle that is its own antiparticletype of:
Definition that contains photon
- h the constant of proportionality relating the energy of a photon to its frequency; approximately 6.626 x 10^-34 joule-second
- einstein physicist born in Germany who formulated the special theory of relativity and the general theory of relativity; Einstein also proposed that light consists of discrete quantized bundles of energy (later called photons) (1879-1955)
- feynman United States physicist who contributed to the theory of the interaction of photons and electrons (1918-1988)
- yukawa Japanese mathematical physicist who proposed that nuclear forces are mediated by massive particles called mesons which are analogous to the photon in mediating electromagnetic forces (1907-1981)
- qed a relativistic quantum theory of the electromagnetic interactions of photons and electrons and muons
- scintillation (physics) a flash of light that is produced in a phosphor when it absorbs a photon or ionizing particle
- scintillate physics: fluoresce momentarily when struck by a charged particle or high-energy photon
- photoelectron an electron that is emitted from an atom or molecule by an incident photon
- pair production the transformation of a gamma-ray photon into an electron and a positron when the photon passes close to an atomic nucleus
- quantum electrodynamics a relativistic quantum theory of the electromagnetic interactions of photons and electrons and muons
