What happens when a beam of light is passed through a colloidal sol.

उत्तर
- When a beam of light is passed through colloidal sol, it is observed that the colloidal particles scatter some of the incident light in all directions.
- Because of this scattering of light, the path of light through the colloidal dispersion becomes visible to an observer standing at right angles to its path, and the phenomenon is known as the Tyndall effect.
