Editing Rayleigh scattering (section)

==Of sound in amorphous solids==
Rayleigh scattering is also an important mechanism of wave scattering in [[amorphous solids]] such as glass, and is responsible for acoustic wave damping and phonon damping in glasses and granular matter at low or not too high temperatures.<ref>{{cite journal |last1=Mahajan |first1=Shivam |last2=Pica Ciamarra |first2=Massimo |title=Quasi-localized vibrational modes, boson peak and sound attenuation in model mass-spring networks |journal=SciPost Physics |year=2023 |volume=15 |issue=2 |page=069 |doi=10.21468/SciPostPhys.15.2.069 |arxiv=2211.01137 |doi-access=free |bibcode=2023ScPP...15...69M }}</ref> This is because in glasses at higher temperatures the Rayleigh-type scattering regime is obscured by the anharmonic damping (typically with a ~''λ''<sup>−2</sup> dependence on wavelength), which becomes increasingly more important as the temperature rises.
