WebOrdinary sunlight is composed of a spectrum of colors that grade from violets and blues at one end to oranges and reds on the other. The wavelengths in this spectrum range from .47 um for violet to .64 um for red. Air molecules are much smaller than this --- about a thousand times smaller. Thus, air is a good Rayleigh scatterer. http://hyperphysics.phy-astr.gsu.edu/hbase/atmos/blusky.html
