WebPhoton is the quantum of light and light is electromagnetic wave which carries momentum and energy. i.e, If the total energy transferred to a surface in time t is U, then p=U/c . So … WebWhat is a Photon? Photon, also known as light quantum, is a minute energy packet of electromagnetic radiation. The idea of photon arose in 1905 from Albert Einstein’s description of the photoelectric effect, in which he suggested the presence of discrete energy packets during the transmission of light.Einstein deduced that the light quantum …
Photon - Definition of Photon, Basic Properties, Applications
WebThe energy of a photon of visible light is very small, being on the order of 4 × 10 −19 joule. A more convenient energy unit in this regime is the electron volt (eV). One electron volt equals the energy gained by an electron when its electric potential is changed by one volt: 1 eV = 1.6 × 10 −19 joule. The spectrum of visible light ...
