Question

Assertion: Tyndall effect is an optical property.
Reason: Scattering of a beam of light by the particles of colloids colloidal is termed as the Tyndall effect.
Select the correct answer from the given options.

  1. Both A and R are true, and R is the correct explanation of A.
  2. Both A and R are true, but R is not the correct explanation of A. 
  3. A is true, and R is false. 
  4. A is false, and R is true

hintHint:

Both A and R are true, and R is the correct explanation of A.

The correct answer is: Both A and R are true, and R is the correct explanation of A.


    The optical property of colloids is known as the Tyndall effect, and the path it takes is known as the Tyndall cone. This effect is caused by light scattering by colloidal particles. A genuine solution does not display the Tyndall effect.
