Photon Momentum Using Frequency
A photon is an elementary particle, the quantum of the electromagnetic field including electromagnetic radiation (such as light) and the force carrier for the electromagnetic force. The momentum of a photon depends only on its frequency.
The momentum equals the Planck constant times the frequency.
