Why Photon have momentum when they do not have mass?
The quantum of EM (Electro-Magnetic) radiation considers a photon has properties analogous to those of particles one can see, such as grains of sand. A photon interacts as a unit in collisions or when absorbed, rather than as an extensive wave. Massive quanta, like electrons, also act like macroscopic particles, because they are the smallest units of matter. Particles carry momentum as well as energy. Despite photons having no mass, there has long been evidence that EM radiation carries momentum. (Maxwell and others who studied EM waves predicted that they would carry momentum.) It is now a well-established fact that photons do have momentum. In fact, photon momentum is suggested by the photoelectric effect, where photons knock electrons out of a substance.
How to Calculate Photon's Momentum using Energy?
Photon's Momentum using Energy calculator uses Photon's Momentum = Photon Energy/[c] to calculate the Photon's Momentum, The Photon's Momentum using Energy formula is defined as the quantity of motion that a photon has to knock electrons out of a substance. Photon's Momentum is denoted by p symbol.
How to calculate Photon's Momentum using Energy using this online calculator? To use this online calculator for Photon's Momentum using Energy, enter Photon Energy (E) and hit the calculate button. Here is how the Photon's Momentum using Energy calculation can be explained with given input values -> 3.4E-7 = 103/[c].
