cross section in scattering is: tex2html_wrap108 where tex2html_wrap109 This is thompson scattering. For tex2html_wrap110 , you get: tex2html_wrap111 .

For Rayleigh scattering, tex2html_wrap112 , tex2html_wrap113 . This is why the sky is blue. Optical loss in fiber optics is mostly rayleigh scattering.
