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 ...
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
Secondly, the photon is now thought of as a particle, a wave, and an excitation—kind of like a wave—in a quantum field. A quantum field, such as the electromagnetic field, is a kind of energy and potential spread throughout space. Physicists think of every particle as an excitation of a quantum field.
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.
Jun 23, 2017 · A photon is the smallest discrete amount or quantum of electromagnetic radiation. It is the basic unit of all light. Photons are always in motion and, in a vacuum, travel at a constant speed to ...

A photon is a type of elementary particle that primarily acts as a carrier of energy. An electron is a subatomic particle that is present in all atoms. A photon has no charge. It possesses a negative charge of magnitude 1.62 × 10 −19 coulomb. It has no rest mass. An electron has a mass of 9.19 × 10 -31 kilograms.
