  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. Rutherford scattering experiments - Wikipedia

    en.wikipedia.org/wiki/Rutherford_scattering...

    The physical phenomenon was explained by Rutherford in a classic 1911 paper [1] that eventually led to the widespread use of scattering in particle physics to study subatomic matter. Rutherford scattering or Coulomb scattering is the elastic scattering of charged particles by the Coulomb interaction.

  4. Extinction paradox - Wikipedia

    en.wikipedia.org/wiki/Extinction_paradox

    In the small wavelength limit, the total scattering cross-section of an impenetrable sphere is twice its geometrical cross-sectional area (which is the value obtained in classical mechanics). [1] Several explanations for this phenomenon have been proposed: [2] destructive interference inside particle shadow [3]

  5. Light scattering by particles - Wikipedia

    en.wikipedia.org/wiki/Light_scattering_by_particles

    Scattering from any spherical particles with arbitrary size parameter is explained by the Mie theory. Mie theory, also called Lorenz-Mie theory or Lorenz-Mie-Debye theory, is a complete analytical solution of Maxwell's equations for the scattering of electromagnetic radiation by spherical particles (Bohren and Huffman, 1998).

  6. Mie scattering - Wikipedia

    en.wikipedia.org/wiki/Mie_scattering

    Mie scattering (sometimes referred to as a non-molecular scattering or aerosol particle scattering) takes place in the lower 4,500 m (15,000 ft) of the atmosphere, where many essentially spherical particles with diameters approximately equal to the wavelength of the incident ray may be present. Mie scattering theory has no upper size limitation ...

  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. Wave–particle duality - Wikipedia

    en.wikipedia.org/wiki/Wave–particle_duality

    In the late 17th century, Sir Isaac Newton had advocated that light was corpuscular (particulate), but Christiaan Huygens took an opposing wave description. While Newton had favored a particle approach, he was the first to attempt to reconcile both wave and particle theories of light, and the only one in his time to consider both, thereby anticipating modern wave-particle duality.

  9. Scattering - Wikipedia

    en.wikipedia.org/wiki/Scattering

    Wine glass in LCD projectors light beam makes the beam scatter.. In physics, scattering is a wide range of physical processes where moving particles or radiation of some form, such as light or sound, are forced to deviate from a straight trajectory by localized non-uniformities (including particles and radiation) in the medium through which they pass.
