This also leads to the fact that if a photon is moving and has energy, it must also have momentum. In the case of the photoelectric effect, the fact that the electron gains momentum when it is hit by a photon must mean that the momentum is transferred from somewhere (from the photon). Formula For The Momentum of a Photon (Complete Derivation)
Momentum (and energy) unifies both causes in one and the same effect. It's an empirical finding that photons have momentum which is being made use of by the solar sail, for instance, and it is a definition of terms to say that photons have "mass", if this is some other way to express the equivalency of both formulas above.
Jul 28, 2023 · Momentum. Momentum is a fundamental property in physics and is defined as the product of the object’s mass and velocity. It is a vector quantity having both magnitude and direction. A car moving on a road has momentum. A soccer ball gathers momentum when it is kicked.
Condensed. I (J P C)=0,1 (1 −−) [ 1 ] A photon (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light') is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force.
What is Photon Momentum? Photon momentum is also known as the momentum of a photon. The momentum of a photon is related to its wavelength, while the energy of a photon is proportionate to its frequency. The below diagram is an illustration of the Compton Effect and the formula is: p = h/λ. Where, p is the momentum of the photon in kg.m/s

Jan 5, 2024 · To fully grasp the concept of momentum, it's important to first understand the basics of motion and forces. In physics, we define momentum as the product of an object's mass and velocity. This means that the more massive an object is and the faster it is moving, the greater its momentum will be. For instance, a car traveling at 60 miles per ...
