Answer:
Milk and starch solution will show Tyndall effect because they are colloids.
A colloid is a kind of solution in which the size of solute particles is intermediate between those in true solutions and those in suspensions.
A colloid is not a true solution.
The scattering of light by colloidal particle is known as tyndall effect.
The scattering of light by Colloidal Solutions tells us that the colloidal particles are much bigger than the particles of a true solution.
True solution does not scatter a beam of light passing through it but a Colloidal solutions scatters a beam of light passing through it.
Colloids are heterogeneous in nature though they appear to be homogeneous.
