State what is meant by a photon
Webphotoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it. In a broader definition, the radiant energy may be infrared, visible, or ultraviolet light, X-rays, or gamma rays; the … WebA photon is produced when an electron releases energy by moving to a lower energy level within the atom. When the atom absorbs energy, it re-emits it in a random direction, …

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, so they always move at the speed … See more The word quanta (singular quantum, Latin for how much) was used before 1900 to mean particles or amounts of different quantities, including electricity. In 1900, the German physicist Max Planck was studying black-body radiation, … See more In most theories up to the eighteenth century, light was pictured as being made up of particles. Since particle models cannot easily … See more In 1924, Satyendra Nath Bose derived Planck's law of black-body radiation without using any electromagnetism, but rather by using a modification of coarse-grained counting of See more Quantization of the electromagnetic field In 1910, Peter Debye derived Planck's law of black-body radiation from a relatively simple assumption. … See more A photon is massless, has no electric charge, and is a stable particle. In a vacuum, a photon has three possible polarization states. The photon is the gauge boson See more Photons obey the laws of quantum mechanics, and so their behavior has both wave-like and particle-like aspects.
