    When a beam of light passes through a true solution, there is no scattering, and the path of light cannot be traced.
    When a beam of light is allowed to pass through a colloid, it gets scattered by the colloidal particles, and the path of the light can be traced.
    The path of light gets illuminated with a bluish light. This phenomenon of scattering of light by colloidal particles is called the Tyndall effect. The illuminated, bright cone of light is called the Tyndall cone.

    Mixture are constituted by two or more kind of pure form of matter . there are two types of mixture are homogeneous and heterogeneous . homogeneous -it is a unifom mixture ,the particle can not be seen from naked eyes, not seperated from filter paper ,do not show tyndall efect for example - solution,sugar in water .heterogeneous - it is a non uniform motion,the particle can be seen by naked eyes,seperated from filter paper ,show tyndall effect for example -suspention,oil in water.by the process of evaporation we know that the watet is pure if no residue is left.
