  2. Rayleigh scattering - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_scattering

    Rayleigh scattering causes the blue color of the daytime sky and the reddening of the Sun at sunset. Rayleigh scattering (/ ˈ r eɪ l i / 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.

  3. Light scattering by particles - Wikipedia

    en.wikipedia.org/wiki/Light_scattering_by_particles

    Multiple-scattering effects of light scattering by particles are treated by radiative transfer techniques (see, e.g. atmospheric radiative transfer codes). The relative size of a scattering particle is defined by its size parameter x, which is the ratio of its characteristic dimension to its wavelength:

  4. Scattering - Wikipedia

    en.wikipedia.org/wiki/Scattering

    Scattering can refer to the consequences of particle-particle collisions between molecules, atoms, electrons, photons and other particles. Examples include: cosmic ray scattering in the Earth's upper atmosphere; particle collisions inside particle accelerators; electron scattering by gas atoms in fluorescent lamps; and neutron scattering inside ...

  5. Cross section (physics) - Wikipedia

    en.wikipedia.org/wiki/Cross_section_(physics)

    In physics, the cross section is a measure of the probability that a specific process will take place in a collision of two particles. For example, the Rutherford cross-section is a measure of probability that an alpha particle will be deflected by a given angle during an interaction with an atomic nucleus.

  6. Dynamic light scattering - Wikipedia

    en.wikipedia.org/wiki/Dynamic_light_scattering

    Dynamic light scattering (DLS) is a technique in physics that can be used to determine the size distribution profile of small particles in suspension or polymers in solution. [1] In the scope of DLS, temporal fluctuations are usually analyzed using the intensity or photon autocorrelation function (also known as photon correlation spectroscopy ...

  7. Rayleigh sky model - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_sky_model

    The Rayleigh sky model describes the observed polarization pattern of the daytime sky. 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.

    Mie scattering (Why clouds are white) Metamerism as of alexandrite; Moiré pattern; Newton's rings; Phosphorescence; Pleochroism gems or crystals, which seem "many-colored" Rayleigh scattering (Why the sky is blue, sunsets are red, and associated phenomena) Reflection; Refraction; Sonoluminescence. Shrimpoluminescence; Synchrotron radiation

  9. John William Strutt, 3rd Baron Rayleigh - Wikipedia

    en.wikipedia.org/wiki/John_William_Strutt,_3rd...

    A type of surface waves are known as Rayleigh waves, and the elastic scattering of electromagnetic waves is called Rayleigh scattering. The rayl, a unit of specific acoustic impedance, is also named for him. Rayleigh was also awarded with (in chronological order): Smith's Prize (1864) Royal Medal (1882) Member of the American Philosophical ...
