Rayleigh scattering other term
WebThe most familiar example of it is scattering of the blue light by air molecules, making sky visible and blue. The light gets diffused, because the direction of the photons scattered by air molecules is random. So, although both diffuse reflection and Rayleigh scattering result in a diffused light, the underlying mechanisms are different. Share. Webrize: molecular scattering consists of Rayleigh scat-tering and vibrational Raman scattering. The Rayleigh scattering consists of rotational Raman lines and the central Cabannes line. …

WebOct 13, 2024 · Rayleigh scattering, named for John William Strutt, 3rd Baron Rayleigh, is how light is scattered through air. Blue light bounces around more than red light, making the sky appear blue. However, this definition, while the most popular, overlaps several different types of scattering, rendering this explanation incomplete.
