Did you know?
Backscattering can occur in quite different physical situations, where the incoming waves or particles are deflected from their original direction by different mechanisms: • Diffuse reflection from large particles and Mie scattering, causing alpenglow and gegenschein, and showing up in weather radar; • Inelastic collisions between electromagnetic waves and the transmitting medium (Brillouin scattering and Raman scattering), important in fiber optics, see b… Backscattering can occur in quite different physical situations, where the incoming waves or particles are deflected from their original direction by different mechanisms: • Diffuse reflection from large particles and Mie scattering, causing alpenglow and gegenschein, and showing up in weather radar; • Inelastic collisions between electromagnetic waves and the transmitting medium (Brillouin scattering and Raman scattering), important in fiber optics, see be… WebRelationships Between Extinction, Absorption, Backscattering, and Mass Content of Sulfuric Acid Aerosols R.
