Question

what is a photon???​

Answer 1

Explanation:

Photons are elementary particles with zero rest mass – necessarily so, since, from special relativity theory, no particle with a finite mass can move at the speed of light.

A photon is the smallest discrete amount or quantum of electromagnetic radiation. It is the basic unit of all light. Photons are always in motion and, in a vacuum, travel at a constant speed to all observers of 2.998 x 108 m/s. ... Essentially, he explained how a stream of photons can act both as a wave and particle.
