Photon momentum is proportional to energy¶

The momentum of a photon is its energy divided by the speed of light.

See Photon energy is proportional to angular frequency or Photon energy is proportional to linear frequency for energy expressions.

Notation:

\(c\) (c) is speed_of_light.

Conditions:

Works in a vacuum environment.
