WebX-rays are basically the same thing as visible light rays. Both are wavelike forms of electromagnetic energy carried by particles called photons (see How Light Works for details). The difference between X-rays and visible … WebPhotons are the fundamental unit (quanta) of light. They have the unique property of being both particle and wave. They are often described as being "bundles of pure energy traveling at the speed of light". And one of the more interesting questions that physicists have raised is whether or not they have mass. They certainly have an energy given ... Photons are massless, so they always move at the speed of light in vacuum, 299 792 458 m/s (or about 186,282 mi/s). The photon belongs to the class of bosons.

In a vacuum, a photon has three possible polarization states. … 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, it is registered as a single, particulate unit. However, the probability of detecting a … Meer weergeven 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 … 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, and he suggested that the … Meer weergeven In most theories up to the eighteenth century, light was pictured as being made up of particles.
