What is Tyndall effect class 9?

The Tyndall effect is the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible. The amount of scattering depends on the frequency of the light and the density of the particles.

Is oil and water a colloid?

What is a colloid in medicine?

Which description is best for a colloid?

Colloids are mixtures in which one or more substances are dispersed as relatively large solid particles or liquid droplets throughout a solid, liquid, or gaseous medium. The particles of a colloid remain dispersed and do not settle due to gravity, and they are often electrically charged.

To identify a colloid mixture from a solution, you can use the Tyndall effect. This is where you pass a light through the mixture. If the light bounces off the particles, you will see the light shine through and you have a colloid mixture.
