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.

Photonen (von griechisch φῶς phōs „Licht“; Einzahl „das Photon“), auch Lichtquanten oder Lichtteilchen, sind anschaulich gesagt die Energie-„Pakete“, aus denen elektromagnetische Strahlung besteht. Physikalisch wird das Photon als Austauschteilchen betrachtet. Nach der Quantenelektrodynamik gehört es als Vermittler der elektromagnetischen Wechselwirkung zu den Eichbosonen und ist somit ein Elementarteilchen. Das Photon hat keine Masse, aber eine Energie und einen Impuls – die beide proportional zu seiner Frequenz sind – sowie einen . Ist sein Aufenthalt auf ein System mit endlichem Volumen beschränkt, liefert es proportional zu seiner Energie einen Beitrag zur Masse des Systems.
