Rayleigh spredning
Rayleigh scattering , named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance … See more In 1869, while attempting to determine whether any contaminants remained in the purified air he used for infrared experiments, John Tyndall discovered that bright light scattering off nanoscopic particulates was … See more The expression above can also be written in terms of individual molecules by expressing the dependence on refractive index in terms of the molecular polarizability α, proportional to the dipole moment induced by the electric field of the light. In this case, … See more The strong wavelength dependence of the scattering (~λ ) means that shorter (blue) wavelengths are scattered more strongly than longer ( See more Rayleigh scattering is an important component of the scattering of optical signals in optical fibers. Silica fibers are glasses, disordered … See more The size of a scattering particle is often parameterized by the ratio where r is the particle's radius, λ is the wavelength of the light and x is a dimensionless parameter that characterizes the particle's interaction with the incident … See more When the dielectric constant $${\displaystyle \epsilon }$$ of a certain region of volume $${\displaystyle V}$$ is different from the average dielectric constant of the … See more 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. This … See more WebRayleigh Scattering definition: The scattering of electromagnetic radiation by particles with dimensions much smaller than the wavelength of the radiation, resulting in angular …

http://dictionary.sensagent.com/Rayleigh%20spredning/no-no/ Rayleigh-spredning, opkaldt efter Baron Rayleigh, er den form for spredning af lys som skabes af partikler der er mindre end lysets bølgelængde: Sådanne partikler spreder blåt og violet lys mere end rødt og gult, fordi blåt lys har kortere bølgelængde end rødt lys. Virkningen kan ses i gennemsigtige faste og flydende stoffer, men er mest udtalt i gasser.
WebOct 7, 2008 · The Rayleigh scattering model showed that, in such systems, the intensity of scattered light varies inversely with the fourth power of its wavelength. In other words, shorter wavelengths — like blue and violet — scatter a lot more than long ones when particles — such as oxygen and nitrogen molecules — are relatively small. WebRayleigh. In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables. Up to rescaling, it coincides with the chi distribution with two degrees of freedom . The distribution is named after Lord Rayleigh ( / ˈreɪli / ).
WebSep 28, 2024 · In an effort to achieve very large Rayleigh numbers when studying turbulence on a Rayleigh--Baposenard configuration, one can carry out simulations and experiments in as high convection cells as possible which involves using convection cells with the smallest possible aspect ratio. However, with the increasing height of the cell, the Rayleigh number … WebRayleigh spredning er mest almindeligt ses i gasser selv om det kan forekomme hos både væsker og faste stoffer. Mængden af spredende foreliggende afhænger polariserende egenskaber af en bestemt type partikel og kan variere afhængigt af de elementer, der er involveret. Mængden af spredning er afhængig af en række faktorer.
