- noun the diversion of light by matter, as seen in the effect Earth’s upper atmosphere has on incoming sunlight, causing the sky to look blue, or the effect of dust or gas nebulae on starlight
- Diversion of light by matter. such as the effect of the Earth’s upper atmosphere on incoming sunlight – which causes the sky to look blue – or the scattering of starlight in dust or gas nebulae Sunlight is scattered very effectively by electrons in the solar atmosphere, and pictures taken on the surface of Mars show that the martian atmosphere, which contains large amounts of dust, tends to scatter light in such as a way as to make red rather than blue skies.
- The process via which electromagnetic radiation, such as light, or particles, such as electrons or neutrons, are spread out, deflected, diffused, or otherwise dispersed after striking or propagating through a surface, region, or medium. sound waves may also undergo such scattering. Specific examples include X-rays being scattered by the atoms in a crystal lattice, or electromagnetic waves being scattered by the ionosphere. When there is a definite phase relationship between the incident and dispersed waves or particles, there is coherent scattering, otherwise it is non-coherent scattering.
- The result of scattering (1).
