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 … Meer weergeven 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 Meer weergeven In most theories up to the eighteenth century, light was pictured as being made up of particles. Since particle models cannot … Meer weergeven In 1924, Satyendra Nath Bose derived Planck's law of black-body radiation without using any electromagnetism, but rather by … Meer weergeven 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 field in a cavity into its Fourier modes, and assumed that the energy in … Meer weergeven 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 Meer weergeven 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, … Meer weergeven In 1916, Albert Einstein showed that Planck's radiation law could be derived from a semi-classical, statistical treatment of photons … Meer weergeven Web31 mrt. 2024 · So, what is a photon in physics? In physics, a photon is a bundle of electromagnetic energy. It is the basic unit that makes up all light. The photon is sometimes referred to as a “quantum” of electromagnetic energy. Photons are not thought to be made up of smaller particles. They are a basic unit of nature called an elementary particle.
