Tyndall effect: The Tyndall effect in opalescent

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 ... Both arise from Tyndall effect or Tyndall scattering - the scattering of light by fine particles dispersed in a light-transmitting medium. If a beam of light passes through an optically transparent dispersion medium, the path of the beam becomes visible when viewed at right angle to the direction of the incident light beam (Figure 1). Learn about the Tyndall effect in chemistry, along with its definition, causes, effects, and applications. Also, learn how this effect is responsible for the blue colour of the eyes. The Tyndall effect is the scattering of light by small particles in a colloid or fine suspension, resulting in a blue color or visible light beam. Learn how to identify colloids, distinguish the Tyndall effect from Rayleigh and Mie scattering, and see examples of the effect in everyday life.
