visible light - Do photons have acceleration?


Photons travel at the fastest speed in our universe, the speed of light.


Do photons have acceleration?



Answer



I think you mean to ask whether a photon can accelerate. The answer is yes. For instance when travelling from one medium to another light changes speeds. In fact, the actual photon is abosrbed and a new photon is reradiated during this process. However, you could call this effectively light acceleration
