WebMie scattering generally refers to scattering by larger particles, with a diameter ≥λ/3. The scattered intensity becomes proportional to ~ λ-2. As the particle size increases relatively to λ, the scattering pattern gradually changes from the symmetrical Rayleigh pattern, to a highly asymmetric one, with forward scattering becoming dominant. Rayleigh approximation (scattering) 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 $${\displaystyle I=I_{0}\left({\frac {1+\cos ^{2}\theta }{2R^{2}}}\right)\left({\frac {2\pi }{\lambda … See more The Mie solution to Maxwell's equations (also known as the Lorenz–Mie solution, the Lorenz–Mie–Debye solution or Mie scattering) describes the scattering of an electromagnetic plane wave by a homogeneous See more The scattering by a spherical nanoparticle is solved exactly regardless of the particle size.

The two most common forms of scattering in the atmosphere are Rayleigh scattering and Mie scattering. Rayleigh scattering is caused by small molecules in the air, and it scatters light more heavily at the shorter wavelengths (blue first, then green, and then red). grape herbalife teagrape health risksWebWhen x<<1 (usually less than 1/10th), Rayleigh scattering mechanisms dominate. As x decreases, the probability that light will scatter off a particular particle drastically decreases.
