I checked. It's not Rayleigh scattering (which accounts for the whiteness of clouds) but Tyndall scattering. However, Rayleigh worked on Tyndall scattering too, so it's loosely called Rayleigh scattering as well. The cloud-is-white effect is also called Mie scattering. It was Einstein who nailed down that N2 and O2 do the work, not dust and particulates. The blue of blue eyes and bluejays is also Tyndall scattering. The sky is not violet because (1) much violet is absorbed in the upper atmosphere and (2) our eyes are less sensitive to violet. -- John Cowan <jcowan@...> I amar prestar aen, han mathon ne nen, han mathon ne chae, a han noston ne 'wilith. --Galadriel, _LOTR:FOTR_
