ans . Tyndall effect is not visible in homogeneous mixture

Q2. The example of suspension is

Ans. Milk is an example of suspension

Q3. Alloys are

Ans . Alloys are homogeneous mixture of metals and cannot be seperated into their components by physical methods. example brass is a mixture of approximately 30% zinc and 70% copper

Q4.colloid do not show

Ans. colloidal solution do not scatter beam of light that's why we can't see light passing through the solution
