Can photons combine
WebApr 6, 2024 · The electrons (and positrons) have 1/2 spin, thus they can annihillate in +1/2, -1/2 or in +1/2, +1/2 configuration. Thus, their summed spin is either 0 or 1. The spin of the photons is 1, also they can opposite or equal sign, … WebPhotons don't combine. Instead (as I've previously mentioned), different photons excite your photo-receptors at different or same time periods. Based on the excitation, the color is observed by you.

WebPair production often refers specifically to a photon creating an electron–positron pair near a nucleus. As energy must be conserved, for pair production to occur, the incoming … WebYou can of course have more than one photon (e.g. a higher number state like 7 ), or superpositions of different numbers of photons (like 1 2 ( 0 + 1 ) ), or more …
If either the electron or positron, or both, have appreciable kinetic energies, other heavier particles can also be produced (such as D mesons or B mesons), since there is enough kinetic energy in the relative velocities to provide the rest energies of those particles. Alternatively, it is possible to produce photons and other light particles, but they will emerge with higher kinetic energies. WebFeb 18, 2024 · In their new work, the researchers wondered whether interactions could take place between not only two photons, but more. “For example, you can combine oxygen …
WebJun 29, 2016 · $\begingroup$ The tensor meson f'(1525) with spin 2 has a 2γ decay mode, so the two photons also combine symmetrically to J=2. By Yang's theorem/symmetry, they cannot combine to J=1, so no vector meson decays to 2 photons. $\endgroup$ – WebStudy with Quizlet and memorize flashcards containing terms like Hydrostatic equilibrium in the Sun means that, The energy that is emitted from the Sun is produced:, The proton-proton chain powers the Sun by fusing hydrogen into helium. As a by-product, several different particles are produced, which eventually produce energy. The process has …
WebIf you shine red light at a nonlinear material, two red photons combine to create an ultraviolet photon. Scientists use this process to stimulate photo-chemical reactions that need high-energy photons, such as …
