Photons are elementary particles that are the fundamental quanta of light and other forms of electromagnetic radiation. They are massless particles, which means they travel at the speed of light (approximately 299,792 kilometers per second or about 186,282 miles per second in a vacuum) and have no rest mass. Photons are also bosons, which means they follow Bose-Einstein statistics and can occupy the same quantum state as other bosons.
