2. Tyndall effect - Wikipedia

   en.wikipedia.org/wiki/Tyndall_effect

   Rayleigh scattering is defined by a mathematical formula that requires the light-scattering particles to be far smaller than the wavelength of the light. [6] For a dispersion of particles to qualify for the Rayleigh formula, the particle sizes need to be below roughly 40 nanometres (for visible light), [ citation needed ] and the particles may ...

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. 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.

5. Transparency and translucency - Wikipedia

   en.wikipedia.org/wiki/Transparency_and_translucency

   Light scattering in liquids and solids depends on the wavelength of the light being scattered. Limits to spatial scales of visibility (using white light) therefore arise, depending on the frequency of the light wave and the physical dimension (or spatial scale) of the scattering center. Visible light has a wavelength scale on the order of 0.5 μm.

6. Mie scattering - Wikipedia

   en.wikipedia.org/wiki/Mie_scattering

   The grey/white colour of the clouds is caused by Mie scattering by water droplets, which are of a comparable size to the wavelengths of visible light. Rayleigh scattering describes the elastic scattering of light by spheres that are much smaller than the wavelength of light. The intensity I of the scattered radiation is given by

7. Dynamic light scattering - Wikipedia

   en.wikipedia.org/wiki/Dynamic_light_scattering

   The general idea is to isolate singly scattered light and suppress undesired contributions from multiple scattering in a dynamic light scattering experiment. Different implementations of cross-correlation light scattering have been developed and applied. Currently, the most widely used scheme is the so-called 3D-dynamic light scattering method.

8. Codes for electromagnetic scattering by spheres - Wikipedia

   en.wikipedia.org/wiki/Codes_for_electromagnetic...

   This program calculates the scattering, absorption, and attenuation parameters, as well as the angular scattering patterns of a single coated sphere according to Aden-Kerker theory. 2007 L. Liu, H. Wang, B. Yu, Y. Xu, J. Shen [15] C: Unknown Light scattering by a coated sphere (extinction efficiency, scattering efficiency, light scattering ...

9. Kramers' opacity law - Wikipedia

   en.wikipedia.org/wiki/Kramers'_opacity_law

   Kramers' opacity law describes the opacity of a medium in terms of the ambient density and temperature, assuming that the opacity is dominated by bound-free absorption (the absorption of light during ionization of a bound electron) or free-free absorption (the absorption of light when scattering a free ion, also called bremsstrahlung).
