The photon is the quantum of the electromagnetic four-potential, and therefore the massless bosonic particle associated with the electromagnetic force, commonly also called the "particle of light". Use this tag for questions about the quantum-mechanical understanding of light and/or electromagnetic interactions.

Can photons only exist in the state of motion in a medium?
Photons are known to travel at a speed of $\rm 299 \ 792 \ 458 \ m / s$ in vacuum. Photons can be absorbed, or absorbed and re-emitted by matter. … What happens if the photons can be virtually brought to a stop and is not absorbed by matter? Can the photon exist in a state where it has an energy of $\rm E = h \nu$, but having no velocity? …
