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. ... Energy, they say, is equivalent to mass according to Einstein's famous formula E = mc2. They also say that a photon has momentum, andmomentum p is related to mass m by p = mv.
