Editing Rayleigh scattering (section)

==History==
In 1869, while attempting to determine whether any contaminants remained in the purified air he used for infrared experiments, [[John Tyndall]] discovered that bright light scattering off nanoscopic particulates was faintly blue-tinted.<ref>{{Cite journal |last1=Tyndall |first1=John |title=On the blue colour of the sky, the polarization of skylight, and on the polarization of light by cloudy matter generally |journal=Proceedings of the Royal Society of London |date=1869 |volume=17 |pages=223–233 |doi=10.1098/rspl.1868.0033|doi-access=free }}</ref> He conjectured that a similar scattering of sunlight gave the sky its [[Diffuse sky radiation|blue hue]], but he could not explain the preference for blue light, nor could atmospheric dust explain the intensity of the sky's color.

In 1871, [[Lord Rayleigh]] published two papers on the color and polarization of skylight to quantify [[Tyndall effect|Tyndall's effect]] in water droplets in terms of the tiny particulates' volumes and [[Refractive index|refractive indices]].<ref>{{cite journal |last1=Strutt |first1=Hon.
