What is the spin of photon - Physics Stack Exchange

WebJun 4, 2015 · Spin is a quantum-mechanical property, akin to the angular momentum of a classical sphere rotating on its axis, except it comes in discrete units of integer or half-integer multiples of ħ. The proton, like the … WebWhen a linearly polarized photon interacts with an electron spin, the Faraday effect results in a rotation of the photon's polarization. For example, take an initially vertically polarized photon that interacts with an electron spin that is either in the "spin up" or "spin down" state.

WebPhotons are spin 1 particles. The spin of a photon is measured by making polarization measurement. If we measure the linear polarization of a single photon along any axis, we can only find it aligned with the axis or perpendicular to this axis. If we measure the linear polarization of photons along any axis, there are only two possible results.

http://jablab2.case.edu/singlephotons.htm Webin which the four-component matrix Dirac equation for a spin one-half electron is adapted to a six-component form of the Maxwell equations for a spin-one photon. This version of the Maxwell equations is a direct extension of the Dirac equation for the electron in which two-by-two Pauli matrices are replaced by analogous three-by-three matrices.

http://electron6.phys.utk.edu/phys250/modules/module%203/spin.htm Photon spin is the quantum-mechanical description of light polarization, where spin +1 and spin −1 represent two opposite directions of circular polarization. Thus, light of a defined circular polarization consists of photons with the same spin, either all +1 or all −1. See more Spin is a conserved quantity carried by elementary particles, and thus by composite particles (hadrons) and atomic nuclei. Spin is one of two types of angular momentum in … See more As the name suggests, spin was originally conceived as the rotation of a particle around some axis.
