WebJul 4, 2016 · If you ask “how big an electron should be” quantum mechanics has an answer. You can guess that an electron should be big enough so that the energy in the electric field is equivalent to the rest mass of the electron (0.511 MeV). If the electron was some sort of charged jell, this would be the size of an pile of charged jell that had the ... WebPhotons and energy. The energy of a photon depends on its frequency.

WebA photon is a purely quantum mechanical object representing the smallest piece of energy (or quanta) for light. Every quantum particle is a packet of energy ... WebOn the Size of a Photon Herbert Weidner a Abstract: After discussing various examples, the diameter of a single photon is calculated by combining the formulas of quantum mechanics and wave theory. The experimentally known coherence length is the length of the photon. History Is light an electromagnetic wave or a stream of photons?
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 of … 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 account for the refraction, diffraction See more In 1924, Satyendra Nath Bose derived Planck's law of black-body radiation without using any electromagnetism, but rather by using a … See more In 1916, Albert Einstein showed that Planck's radiation law could be derived from a semi-classical, statistical treatment of photons and … 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 for electromagnetism, and therefore all other quantum numbers of the photon (such as See more Photons obey the laws of quantum mechanics, and so their behavior has both wave-like and particle-like aspects. When a photon is detected by a measuring instrument, it is registered as a single, particulate unit. However, the probability of detecting a photon … See more Quantization of the electromagnetic field In 1910, Peter Debye derived Planck's law of black-body radiation from a relatively simple assumption. He decomposed the electromagnetic … See more WebDec 24, 2006 · 0. Point particles have a nasty habit of having infinite energy densities , but it is true that QM assumes particles to be point like. Super String Theory assumes all particles to be small strings with a length of just about the Planck length and no width, i.e. one dimensional . In that case a photon is 10e-44 meters.
