In beaker B sawdust and water is taken

b)If light is allowed to pass through both the beakers, which beaker will show scattering of light.
c) What is the above mentioned phenomenon called?​

Answer 1

Answer:

Beaker A will show a path of light (It's a colloidal solution /Heterogeneous mixture). This is because it is the emulsion of milk and water which shows the Tyndall effect.

Beaker B will not show path of light. (It's a homogenous solution) Visibility of light in a mixture is known as Tyndall effect. (And the path is visible because large molecules of heterogeneous mixture deviate the path of light to make it visible)
