Answer 1

we will see Tyndall effect. It will reflect beam of light and we will be able to see path of light.

Answer 2

Answer:

When a light passes through a true solution, containing solute particles of size less thanm1 nm, the path of the light is not visible. If the light is passed through a colloidal solution, the path of the light through the dispersion medium becomes visible due to thenscattering of the light. This is the optical property of the colloids.
