The 121 pages that link to Photon, each with the reason it gives.

• FluorescenceNarrower topic: Absorption and emission occur through interactions involving individual photons.

• Photoelectric effectNarrower topic: Einstein explained the effect by treating light as discrete energy-carrying quanta.

• LaserNarrower topic: Stimulated emission adds photons with the same frequency and direction as the triggering photon.

• Compton scatteringNarrower topic: Compton’s explanation treated X-rays as particles with quantized energy and momentum.

• PhotochemistryNarrower topic: Its energy sets which molecular transitions can be initiated by light.

• X-rayNarrower topic: An X-ray is one photon in the high-energy part of the spectrum.

• ChromophoreNarrower topic: A chromophore absorbs light by taking up photons with suitable energies.

• PhotoluminescenceNarrower topic: Photons provide the excitation energy and are released during radiative emission.

• Stimulated emissionNarrower topic: The incoming photon triggers the transition, and the emitted photon joins the radiation field.

• PhotoionizationNarrower topic: Absorbing a photon provides the energy that can remove a bound electron.

• PhotolysisNarrower topic: A photolysis event begins when a molecule absorbs a photon's energy.

• Quantum yieldNarrower topic: Quantum yield uses photons as the units counted in its denominator and often its numerator.

• InfraredNarrower topic: Infrared photons carry less energy than visible-light photons because their frequencies are lower.

• Inverse Compton scatteringNarrower topic: Its initial energy and direction determine the energy transferred during the collision.

• ElectroluminescenceNarrower topic: Each emitted light quantum is a photon.

• Hydrogen spectral seriesNarrower topic: Each emitted line corresponds to a photon whose energy equals the transition's energy difference.

• Photochemical reactionNarrower topic: Its energy is absorbed to initiate or alter the reaction.

• Quantum efficiencyNarrower topic: Quantum efficiency counts photons rather than measuring optical power alone.

• Gamma decayNarrower topic: The emitted gamma ray is a photon produced by a nuclear transition.

• PhotodissociationNarrower topic: A photodissociation event begins when a molecule absorbs a photon.

• Photosynthetically active radiationNarrower topic: PAR is often quantified as a flux of photons rather than radiant energy.

• Lyman seriesNarrower topic: Each downward transition emits a photon whose energy matches the level difference.

• Photon momentumNarrower topic: Photon momentum is a property of this massless quantum.

• OptoelectronicsNarrower topic: Photon energy links optical wavelength to electronic transitions in device materials.

• Hong–Ou–Mandel effectNarrower topic: The effect concerns the joint output statistics of individual photons.

• PhotonicsNarrower topic: Photonics controls light, whose energy is exchanged in quantized units.

• BiophotonNarrower topic: A biophoton is a photon distinguished by its biological source, not a different kind of particle.

• Gamma-ray techniquesNarrower topic: Gamma rays are photons distinguished by their origin and energy range.
