WebApr 7, 2024 · Rayleigh or Selective Scattering Rayleigh scattering of light is a type of elastic scattering as the particle from which the scattering has to be done depends on the wavelength of light. 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, proportional to the dipole moment induced by the electric field of the light. In this case, … 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 materials with microscopic … 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 … See more

Why is the sky blue? - Met Office

WebWell, the short answer for this is because the molecules of our atmosphere, like the nitrogen molecules or the oxygen molecules, tend to scatter blue light more than red. So let's explore this in a little bit more detail. We've talked about scattering of light in previous videos. WebRayleigh Scattering (Why is the Sky Blue?)
