Which of the following will show “Tyndall effect”?

(a) Salt solution

(b) Milk

(c) Copper sulphate solution

(d) Starch solution



The scattering of light by the colloid particles is known as the tyndall effect. 

Hence, it can be concluded that colloids show tyndall effect because their particles are large enough to scatter the beam of light passing through them. 

Milk and starch solution are colloids, hence they show tyndall effect.
