A photon () is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless particles that can only move at one speed, the speed of light measured in a vacuum. The photon belongs to the class of boson particles.

OverviewAI-generated

A photon is a particle with a spin quantum number of 1 and an electric charge of 0. It has a mass of 0.000000000000000000001 and a mean lifetime of 1. The particle possesses a charge conjugation quantum number of -1 and a parity quantum number of -1. Its half-life is also recorded as 1.

The concept was discovered or invented in 1923. In academic literature, the term appears in 326,409 PubMed records. It is referenced by 2,045 other encyclopedia articles. The subject is categorized under the Commons category "Photon" and carries the Monte Carlo Particle Number 22.
