- Photon - Wikipedia
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
- What are photons? - Live Science
Photons are fundamental subatomic particles that carry the electromagnetic force — or, in simpler terms, they are light particles (and so much more) The photon is also the "quantum," or
- What Is a Photon? Definition and Facts - Science Notes and Projects
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 Photons have the following properties: A photon has zero rest mass However, because it is moving, it has momentum
- Photon | Definition, Discovery, Charge, Facts | Britannica
photon, minute energy packet of electromagnetic radiation The concept originated (1905) in Albert Einstein ’s explanation of the photoelectric effect, in which he proposed the existence of discrete energy packets during the transmission of light
- What Is a Photon? The Quantum Particle of Light
The answer, unveiled through the birth of quantum mechanics, is that light is composed of tiny packets of energy called photons These quantum particles of light challenge our classical intuition, revealing a universe far more fascinating and peculiar than everyday experience suggests

Photons carry energy in quantized, fixed amounts, known as ‘quanta,’ rather than in a continuous flow in small, specific, meaning discrete packets of energy
- What Is a Photon in Physics? - ThoughtCo
A photon is a tiny particle of light that always moves at the speed of light Photons act like both waves and particles at the same time, which is a special property Photons have no mass, but they carry energy and momentum that link to their frequency and wavelength
