Does a photon travel at the speed of light

WebMar 10, 2024 · Photons have zero mass, which allows them to travel at the fastest possible speed in the universe, the speed of light. However, they do have energy and momentum. WebJul 17, 2011 · No particle has rest mass, but the string as a whole can obtain mass if the particle is vibrating at the speed of light, given by hf/c^2 where h=planck length, f=frequency, c=speed of light. The string for a photon does not have mass, therefore vibrations on the photon string are slower than light. Jul 17, 2011. #7.
