Does All Electromagnetic Radiation Have Photons

Physics if every type of radiation visible light radio waves x rays etc is just a different frequency in the spectrum does that mean every wave is comprised of photons and travels at the speed of light like visible light. All bodies emit infrared radiation.

Many other kinds of ionizing radiation are made of non em particles.

Does all electromagnetic radiation have photons. These waves do have energy and momentum by the way. The question why is not so easy to answer. The different types of radiation are defined by the the amount of energy found in the photons.

What is electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass less particles called photons each traveling in a wave like pattern at the speed of light. They obey the maxwell equation partialmu fmu nujnu.

A photon is the smallest discrete amount or quantum of electromagnetic radiation. Photons are always in motion and in a vacuum travel at a constant. It is the basic unit of all light.

Radio waves have photons with low energies microwave photons have a little more energy than radio waves infrared photons have still more then visible ultraviolet x rays and the most energetic of all gamma rays. There is no need for a particle concept there the classical theory of continuous fields can deal with energy and momentum just fine. Electromagnetic radiation composed of photons that carry minimum ionization energy or more which includes the entire spectrum with shorter wavelengths is therefore termed ionizing radiation.

There are only continuous electromagnetic waves their behavior governed by maxwells beautiful equations. The photon is the u1 gauge boson so it has to have integer spin. Are all electromagnetic waves carried by photons like visible light.

Like all elementary particles photons are. It always moves at the speed of light in a vacuum. Em radiation is the sum of all emitted photons from the involved electrons protons and neutrons of a body.

5000c they emit visible light first glowing in red and then shining brighter and brighter. Radio waves gamma rays visible light and all the other parts of the electromagnetic spectrum are electromagnetic radiation. The photon is a type of elementary particleit is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves and the force carrier for the electromagnetic force even when static via virtual particlesthe invariant mass of the photon is zero.

Photons are spin 1 particles they can be polarized in two different ways circular left und right like electromagnetic waves. Each photon contains a certain amount of energy.
