Momentum Of Photon Formula

Momentum of Photon Formula

A photon’s momentum is inextricably linked to its energy. Similarly, a Momentum Of Photon Formula and energy is related to its wavelength and frequency. The equation p = h/λ can be used to determine a photon’s momentum.

Momentum of Photon

With the Momentum of Photon Formula, Einstein described the momentum of photon = h/λ where, p = the momentum of the photon (measured in Kg.m/s), h = Planck’s constant has a value of 6.63×10−34 J ⋅ s, and λ = the wavelength of the wave bearing the photon in meters.

The photon’s momentum is typically negligible due to the low value of “h” in most situations. The mirror doesn’t pull back when photons bounce off of it, which supports this.

Momentum of Photon Formula

Positively charged and massless, a photon is a particle that moves at the speed of light in a vacuum. A Momentum Of Photon Formula is defined as the amount of strength or energy it gains while in motion. It is denoted by the symbol p and is equal to the photon’s mass and velocity product. It has both magnitude and direction because it is a vector quantity. Kg/m/s, or kilogram per metre per second, is the unit of measurement.

Importance of Momentum of Photon Formula

Photons are important particles in quantum mechanics. Photons make up light and other types of rays. The idea was first made public by Albert Einstein, a scientist. In the field of physics, it signalled a new era.
