Per NCERT, what is the TYNDALL EFFECT?
AThe complete absorption of light by a solution
BThe dissolving of one substance in another
CThe visible scattering of a beam of light when it passes through a colloid — caused by the colloid's particles being just the right size to scatter light
DThe change of colour when light hits a true solution
Answer & Solution
Correct answer: C. The visible scattering of a beam of light when it passes through a colloid — caused by the colloid's particles being just the right size to scatter light
Per NCERT §5.5, the Tyndall effect is light scattering by colloidal particles — distinguishes colloids from true solutions.
