Rayleigh scattering pattern
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 … 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 materials with microscopic variations of density and refractive index. These give rise to energy losses due to the … 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 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 … See more WebRayleigh scattering scattering of light by particles that are less than 1/15 of the wavelength of the light. Atoms and ordinary molecules which have a diameter of less than one nanometer are included in Rayleigh scattering. - When light travels through a medium, it interacts with the medium and this causes the scattering of light.

Within the atmosphere, Rayleigh scattering of light by air molecules, water, dust, and aerosols causes the sky's light to have a defined polarization pattern. The same elastic scattering processes cause the sky to be blue. The polarization is characterized at each wavelength by its degree of polarization, an…
WebThe Rayleigh scattering function is symmetric, with maxima at 0° and 180° while minima appear at 90° and 270°. In the Mie region, the scattering pattern becomes more anisotropic and forward scattering dominates more as the particle size increases.
