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.
1 day 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?)
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.

Mar 10, 2022 · Even though only one photon passes through the screen at a time — with each individual photon acting like a particle — the interference pattern that emerges on the detector is the exact same ...
Jun 27, 2024 · 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. Fast Facts. Photons can be absorbed by matter. When this happens, their light is transformed into heat, warming the matter.

Dec 10, 2023 · Since every photon of sufficient energy excites only one electron, increasing the light's intensity (i.e. the number of photons/sec) only increases the number of released electrons and not their kinetic energy. In addition, no time is necessary for the atom to be heated to a critical temperature and therefore the release of the electron is nearly instantaneous upon absorption of the light.
