The angle through which radiation is dispersed in this phenomenon varies inversely by the fourth power of wavelength, enhancing the shorter wavelengths.  
The angle through which radiation is dispersed in this phenomenon varies inversely by the fourth power of wavelength, enhancing the shorter wavelengths.  It can be considered elastic, because the energies of the scattered photons are not changed, and it specifically refers to interactions with molecules with diameters less than 1/10 of the wavelength.  FTP, name this type of scattering discovered by its namesake in 1871 that accounts for why the sky is blue.
