A photon (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light') 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 always move at the speed of light ...
23 hours ago · A photon is the most basic, discrete packet of energy that light or any electromagnetic wave can exist in. It is an elementary particle with no mass and no electric charge, yet it carries both energy and momentum, allowing it to travel through space and interact with matter. Historical Development
May 23, 2020 · So according to google: a photon is a particle that transmits light. A photon is a particle that transmits energy and has a momentum. Human perception interprets some part of the EM radiation as light. Ok, but light is considered a wave, not a stream of particles (I'm pretty sure that this is what Young's double slit experiment proved?)
This is the way a sheet of metal emits electrons when hit with light. Einstein demonstrated that the intensity of the light shined on the metal is tied to the number of photons in the light. The frequency (or color) of the light is tied to the amount of energy each photon carries. DOE Office of Science: Contributions to Subatomic Particle Research
Mar 10, 2022 · The energy of a photon is given by Planck's constant times the frequency of the light, and the momentum of a photon is given by Planck's constant times the frequency of the light times the speed ...
Dec 21, 2023 · When two electrons interact, they exchange a photon, the particle of light. (Image: Ana Tovar/CERN) Across the electromagnetic spectrum, photons serve as an omnipresent probe and tool with broad research and practical applications. Low energy radio photons transmit information through fiber optic cables and free space.

Dec 14, 2022 · A photon is a unit of light. It is a quantum or packet with no rest mass, yet with momentum. A photon is a packet or quantum of light and the force carrier of the electromagnetic force. It is an elementary particle. Like other elementary particles, photons display properties of both particles and waves.
