Absorption and Emission
Taking the electron transitions associated with visible and ultraviolet interactions with matter as an example, absorption of a photon will occur only when the quantum energy of the photon precisely ...

Stimulated Emission
If an electron is already in an excited state, then an incoming photon for which the quantum energy is equal to the energy difference between its present level and a lower level can "stimulate" a ...

Compton Wavelength
The scattering of photons from charged particles is called Compton scattering after Arthur Compton who was the first to measure photon-electron scattering in 1911. When the incoming photon gives part ...

Debroglie Wavelength
Suggested by De Broglie in about 1913, the path to the wavelength expression for a particle is by analogy to the momentum of a photon. The momentum-wavelength relationship for a photon can be derived ...
