"WebIn the case of light, incoherent scattering is called “Rayleigh” scattering when it is elastic. It is a common process that makes us see objects with our eyes, which detect light scattered by these objects. Thus leaves appear green as chlorophyll pigments scatter green light, while it absorbs blue and red lights and is transparent for green light. " - Incoherent scattering function
