Rayleigh scattering (/ ˈreɪli / RAY-lee) is the scattering or deflection of light, or other electromagnetic radiation, by particles with a size much smaller than the wavelength of the radiation.

Rayleigh scattering where the wavelength is long, the scattered power is distributed isotrop-ically save for the doughnut shape of the radiation pattern, namely, the sin2( ) dependence.

Mar 31, 2025 · Rayleigh scattering, dispersion of electromagnetic radiation by particles that have a radius less than approximately 1/10 the wavelength of the radiation. The process has been named in honour of Lord Rayleigh, who in 1871 published a paper describing this phenomenon.

Aug 31, 2023 · Rayleigh scattering formula provides a quantitative explanation for the intensity of light scattered by particles much smaller than the wavelength of the incident light. According to Rayleigh’s law, the intensity of scattered light is inversely proportional to …

Formal light scattering theory may be categorized in terms of two theoretical frameworks. One is the theory of Rayleigh scattering (after Lord Rayleigh) that is, strictly speaking as originally formulated, applicable to small, dielectric (non-absorbing), spherical particles.

Jan 1, 2016 · Rayleigh scattering refers primarily to the elastic scattering of light from atomic and molecular particles whose diameter is less than about one-tenth the wavelength of the incident light. Rayleigh line refers to the unshifted central peak observed in …

The mathematical theory of Rayleigh scattering must take into account the wavelength of the light, the size and shape of the region the semi-mobile electrons can move around in, how tightly bound they are to the atom's nucleus, and how many of them there are in a molecule.

May 28, 2024 · Explore the cause, effect, and optical principles of Rayleigh Scattering, the phenomenon behind the blue sky and colorful sunsets. Rayleigh Scattering is a fundamental concept in optics that explains why the sky appears blue and the sunset red.

Oct 10, 2017 · This post introduces the Mathematics of Rayleigh Scattering, which is the optical phenomenon that causes the sky to appear blue.

Mar 27, 2024 · Approximate theory for electromagnetic scattering by small particles named for Lord Rayleigh (John William Strutt, 1842–1919), who in 1871 showed that the blue color of the clear sky is explained by the scattering of light by molecules in the atmosphere.
