Question
What can be observed when the sunlight passes through a colloidal solution?
- Coagulation
- Absorption
- Tyndall effect
- Evaporation
Hint:
Tyndall effect
The correct answer is: Tyndall effect
The scattering of light is when a light beam passes through a colloid is known as the Tyndall effect. Individual suspension particles scatter and reflect light, allowing the beam to be seen.
