WebThe angular dependence of scattered light, P(X), from randomly branched homopolycondensates was calculated by using moment-generating functions.Analytical expressions could be derived both for Gaussian sub-chains and for sub-chains obeying random flight statistics. WebThe scattered light can also be shown to be polarised using a filter of polarised light, just as the sky appears a deeper blue through polaroid sun glasses. This is most correctly called the Tyndall effect, but it is more commonly known to physicists as Rayleigh scattering—after Lord Rayleigh, who studied it in more detail a few years later.

WebHowever, the eyes of many insects are responsive to polarization properties, and they use the relative polarization of ambient sky light as a navigational tool. A common camera filter employed to reduce background light in bright sunshine is a simple linear polarizer designed to reject Rayleigh scattered light from the sky.
