The phenomenon that occurs when radiation is scattered predominantly backwards along its original path. Rayleigh scattering and Thomson scattering generate equal amounts of forward and backscattering. Particular cases of backscattering are the rainbow, and the heiligenschein from dew on grass which appears as a halo around the head of the observer's shadow. See also forward scattering.
