Answer :

A mixture of sulphur and carbon disulphide is heterogeneous and shows Tyndall effect.

A mixture of sulphur and carbon disulphide is a heterogeneous colloid* and shows Tyndall effect. The Tyndall effect is scattering of light by particles in a colloid. Colloids appear to be homogeneous but they are actually heterogeneous in nature. Milk and fog are some other examples of colloids.

*Colloids are the substances that have some other substances dispersed in the solution and these particles do not settle down at the bottom.
