Rayleigh reflection
Rayleigh scattering , named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance … See more In 1869, while attempting to determine whether any contaminants remained in the purified air he used for infrared experiments, John Tyndall discovered that bright light scattering off nanoscopic particulates was … See more The expression above can also be written in terms of individual molecules by expressing the dependence on refractive index in terms of the molecular polarizability α, … See more The strong wavelength dependence of the scattering (~λ ) means that shorter (blue) wavelengths are scattered more strongly than longer (red) wavelengths. This results in the … See more Rayleigh scattering is an important component of the scattering of optical signals in optical fibers. Silica fibers are glasses, disordered … See more The size of a scattering particle is often parameterized by the ratio where r is the particle's radius, λ is the wavelength of … See more When the dielectric constant $${\displaystyle \epsilon }$$ of a certain region of volume $${\displaystyle V}$$ is different from the average dielectric constant of the … See more Rayleigh scattering is also an important mechanism of wave scattering in amorphous solids such as glass, and is responsible for acoustic wave damping and phonon damping in glasses and granular matter at low or not too high temperatures.

WebThe effects of reflections on the radio channel are very important in propagation studies. We will start off by looking at the simplest case of a reflection from a smooth flat surface of infinite extent. This is one of those cases that does not really exist, but as long as the surface is large compared to the size of the Fresnel zone, it will ...
