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.
17 hours ago · This means that each photon has a set amount of energy that comes in discrete packets, depending on its frequency. We can calculate a photon’s energy using the equation: E = hν. where – E is the energy – ν is the frequency – h is Planck’s constant . The higher the frequency of a photon, the more energy it has.
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 ...
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.
Sep 3, 2018 · Updated on September 03, 2018. A photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic (or light) energy. Photons are always in motion and, in a vacuum (a completely empty space), have a constant speed of light to all observers. Photons travel at the vacuum speed of light (more commonly just called the speed ...
