Explain what is observed (i) when a beam light is passed through a colloidal sol.
When a beam of light is passed through a colloidal solution, a scattering of light is observed which is known as the Tyndall effect. With the scattering of light, the path of the beam gets illuminated in the colloidal solution. Final Answer When a beam of light is passed through a colloidal solution, a scattering of light is observed which is known as the Tyndall effect.
