Scattering
Scattering (/ˈskætərɪŋ/) is a general physical process where some forms of radiation, such as light, sound, or particles are forced to deviate from a straight trajectory by one or more paths due to localized non-uniformities in the medium through which they pass.
Etymology
The term "scattering" is derived from the Middle English scateren, meaning "to disperse".

- Reflection: The change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.
- Refraction: The change in direction of a wave passing from one medium to another caused by its change in speed.
- Absorption: The way in which the energy of a photon is taken up by matter, typically the electrons of an atom.
