Question

Explain the following with the help of diagram
(i) Tyndall effect
(ii) Brownian movement.

Answer 1

Answer:

•The size of colloidal particles are too small to be seen by naked eyes however they exist a property known as tyndall effect.

•The zigzag motion of colloidal particles is called Brownian movement.

Explanation:

hope this answer helps you

Answer 2

The phenomenon of scattering of light when a light beam passes through a fluid (colloid) is known as Tyndall effect, while the random movement of particles in a fluid (colloid) is the Brownian motion, it occurs due to the collisions of the particles.

◆ 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.
