Question

explain tyndall effect and brownian movement with suitable diagram

Answer 1

Colloidal particles move in zig – zag path. This type of motion is due to colliding molecules of dispersion medium constantly with colloidal particles.

Tyndall effect: The scattering of a beam of light by colloidal particles is called Tyndall effect. The bright cone of light is called the Tyndall cone.

Answer 2

Dear Student,

◆ Tyndall effect -

• Tyndall effect is scattering of a beam of light by the particles of a colloid.

◆ Brownian motion -

• Brownian motion is random motion of fluid particles bombarding on each other.

# For example -

• Milk being a colloid (liquid fat in water), shows Tyndall effect.
• When beam of light is passed through milk, it's scattered through the milk.
• Here, path of light becomes visible due to Tyndal effect.

Thanks dear. Hope this helps you...
