Tyndall effect
This is light scattering by particles in a colloid or in a very fine suspension.
It is applicable to colloidal mixtures or fine suspensions.
From the given choices:
1) Magnesium hydroxide is an homogenous mixture hence Tyndall effect does not occur.
2) Sugar solution is a homogenous mixture hence Tyndall effect does not occur.
3) Flour in water is a suspension and hence Tyndall effect occurs.
From above analysis, the answer is :
Flour in water
flour in water is the answer
