Learn what the Tyndall effect is, how it occurs, and why it is important for colloids and eye colour. Find out the difference between Tyndall effect and other types of light scattering, and test your knowledge with a quiz. The Tyndall Effect is a fascinating optical phenomenon that occurs when tiny particles scatter light in a medium. It can be understood as the interaction between light and matter on a microscopic scale. When a beam of light encounters particles or molecules in a medium, the individual photons interact with these particles, causing them to scatter in various directions [1-4]. The Tyndall effect in opalescent glass: it appears blue from the side, but orange light shines through. [1] The Tyndall effect is light scattering by particles in a colloid such as a very fine suspension (a sol). 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 than red light. An example in everyday life is the blue ... Tyndall effect , scattering of a beam of light by a medium containing small suspended particles—e.g., smoke or dust in a room, which makes visible a light beam entering a window. As in Rayleigh scattering, short-wavelength blue light is scattered more strongly than long-wavelength red light.
