How is a photon massless

WebAre photons massless? Light is composed of photons, so we could ask if the photon has mass. The answer is then definitely “no”: the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits. WebPhotons are particles that have no weight and are thus massless. They are the particles responsible for carrying energy in the form of electromagnetic waves. When a particle …
