What is the momentum of light? |
|
Answer» The rest mass of photon is zero. Not the moving mass. 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, and momentum p is related to mass m by p = mv. |
