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]. 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 what the Tyndall effect is, how it occurs, and why it is a property of colloids. See examples of the Tyndall effect in milk, fog, eyes, and more. The Tyndall effect is when light scatters as it passes through a colloid, making the light beam visible. Examples of the Tyndall effect include blue smoke from engines and visible headlights in fog. To see the Tyndall effect at home, you can mix flour or cornstarch in water to scatter light.
