WebIn general, the two terms are different: the infrared radiation is defined by having the wavelength in the fixed interval 0.7 - 300 micrometers (a convention) while the thermal radiation of an object depends on its absolute temperature T. While any object at nonzero temperature emits at all wavelengths, the wavelength at which the emission is ... 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 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 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. When a photon is detected by a measuring instrument, it is registered as a single, particulate unit. However, the probability of detecting 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 atoms, which implies a link between the rates at which atoms emit and absorb photons. The condition follows from the … See more WebMar 21, 2024 · A photon has a dual nature, as a particle and as an EM wave.
