    Light scattering in colloidal solutions or particles in suspension is known as Tyndall Effect. It is similar to Rayleigh scattering, in that the intensity of the scattered light depends on the fourth power of the frequency, so blue light is scattered much more strongly than red light.

    Correct Option: A
