Rayleigh scattering particle size
WebJan 24, 2024 · Rayleigh scattering occurs when the scattering particle’s largest dimension is less than 5% of the radiation’s wavelength. The intensity of the scattered radiation is … WebApr 27, 2024 · , which can be computed using different scattering theories. 2.1 Rayleigh theory If particle size is much less than light wavelength, all elementary dipoles of particle emit coherently. This case of scattering is named after Lord Rayleigh who determined the dependence of the intensity of scattered light on the wavelength in 1871.
