THIS ARTICLE TALKS ABOUT LIGHT AS A PARTICLE!


Photons

Photons are special particles that carry energy in the form of light. This article will talk about why light is a particle and not a wave. Remember, that scientists consider light to be both a wave and a particle!


Photons are gauge bosons, because they have a spin of 1. Photons are the baryons that carry the electromagnetic force, although there is a possibility that photons don't exist, and the electromagnetic force is carried by the electromagnetic wave. To put it simply, light is an electromagnetic wave / photon with frequencies that humans can see. The types of electromagnetic waves / photons are (from shortest to longest frequencies) gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves and radio waves.


Photons have no mass, yet they have energy and momentum


Proof that light is a particle

Some proof that light is a particle is the photoelectric effect which we will talk about later. Also, the fact that light may have mass proves that light is a particle. There are many more reasons why light is a particle so you may have to keep re-visiting this site to stay up to date with the info posted here.
