Incorrect statement for Tyndall effect is :

The refractive indices of the dispersed phase and the dispersion medium differ greatly in magnitude.

The diameter of the dispersed particles is much smaller than the wavelength of the light used.

During projection of movies in the cinemas hall, Tyndall effect is noticed.

It is used to distinguish a true solution from a colloidal solution.

Using very little soap while washing clothes, does not serve the purpose of cleaning of clothes, because :

soap particles remain floating in water as ions.

the hydrophobic part of soap is not able to take away grease.

the micelles are not formed due to concentration of soap, below its CMC value.

colloidal structure of soap in water is completely disturbed.
