Here’s a explanation:
Tyndall Effect
- Definition: The Tyndall effect is the scattering of light by tiny particles in a colloid, making the path of the light beam visible.
- Reason: Colloidal particles are big enough to scatter light, unlike true solutions.
Examples:
- Sunlight passing through fog or dust.
- A beam of light in milk or gelatin.
Simple tip:
- Colloids scatter light → visible beam
- Solutions do not → beam not visible
