Faraday-Tyndall Effect

The Faraday-Tyndall Effect describes how tiny particles in a suspension scatter light when illuminated, making the path of the light visible. Named after scientists Michael Faraday and John Tyndall, this effect occurs because particles larger than the wavelength of light deflect the beam, creating a visible glow or beam within the fluid. It helps distinguish between true solutions (which don't scatter light) and colloids or suspensions (which do). This phenomenon is similar to seeing a laser beam through fog or smoke, where particles scatter the light, revealing its presence.
