WebLecture Slides - Michigan Technological University WebMie scattering occurs when the scattering particles have a similar size as the wavelength of light. Here, one has significant variations of optical phase over the scattering contributions of different locations on the particles. Here one finds that – in contrast to Rayleigh scattering – the scattering intensity does not depend that much on the optical …

WebFeb 21, 2008 · Scattering of light (Tyndall effect and, closely related, Rayleigh scattering) can thus be observed quite frequently. The iris of the human eye does not contain any blue pigment or dye. The turbid front layer, if it contains no or only little melanin, appears blue in front of the dark back layer due to the preferred scattering of light with short wavelengths. WebRayleigh scattering; Mie scattering; Nonselective scattering; Rayleigh scattering occurs when particles are very small compared to the wavelength of the radiation. These could be particles such as small specks of dust or nitrogen and oxygen molecules. Rayleigh scattering causes shorter wavelengths of energy to be scattered much more than longer ...

WebAug 6, 2024 · Inelastic scattering is further classified into four types: Rayleigh Scattering: When radiation (light) interacts with molecules and particles in the atmosphere that have a smaller diameter than the wavelength of the incoming radiation, Rayleigh scattering occurs.
