Question

Tyndall effect in colloidal solution is due to:

• A. absorption of light
• B. scattering of light
• C. reflection of light
• D. presence of electrically charged particles

Answer 1

The correct option is B scattering of light

When a strong and converging beam of light is passed through a colloidal solution, its path becomes visible when viewed at right angles to the beam of light . This effect is called Tyndall effect and it is due to the scattering of light by the colloidal particles.
