The Tyndall effect is light scattering by particles in a colloid or in a very fine suspension. Also known as Tyndall scattering, it is similar to Rayleigh scattering, in that the intensity of the scattered light is inversely proportional to the fourth power of the wavelength, so blue light is scattered much more strongly … See more Prior to his discovery of the phenomenon, Tyndall was primarily known for his work on the absorption and emission of radiant heat on a molecular level. In his investigations in that area, it had become necessary to use … See more A blue iris in an eye is blue due to Tyndall scattering by a translucent layer of turbid media in the iris that contains numerous small particles, which are about 0.6 micrometers in … See more • Light scattering • Transparency and translucency • Ultramicroscope See more Rayleigh scattering is defined by a mathematical formula that requires the light-scattering particles to be far smaller than the wavelength of the light.
