Here’s a explanation of the Tyndall effect:
Tyndall Effect
- Definition: When a beam of light passes through a colloidal solution, the light gets scattered by the tiny particles, making the path of light visible.
- Reason: Colloidal particles are big enough to scatter light, unlike in true solutions where light passes straight through.
- Observation: You can see the light beam in the colloid, but not in a true solution.
Examples:
- Sunlight passing through fog or dusty air
- A beam of light in milk or gelatin solution
Simple tip:
- Colloids scatter light → Tyndall effect
- Solutions don’t → no visible beam
