Coulson solved Chandrasekhar's X and Y functions for this process when a Lambert surface was underneath.  The Babinet point is an example of a neutral point predicted by the theory of this effect. It is inversely proportional to the fourth power of the wavelength of the light. This process predominates when the size of the particle is much smaller than the wavelength. This effect is seen as light travels through transparent solids and liquids, but is most noticeable in gases. This effect is enhanced for short wavelengths. For 10 points, name this elastic process named for British scientist that causes the sky to appear blue.
