Which of the following will show Tyndall effect?
Tyndall effect is the phenomenon of scattering of light by the particles of colloid or suspension because of which the path of light is illuminated. The tiny particles scatter the beam of light and make its path visible. For example, the Tyndall effect can be observed when sunlight passes through the canopy of a dense forest. In the forest, mist contains tiny droplets of water, which act as particles of colloid dispersed in the air.
The particles of dust and smoke in the air scatter light, thereby causing the Tyndall effect. It was first observed by physicist John Tyndall.
It is also shown by the mixture of milk in water.
Hence, the correct option is (C).
