प्रश्न
What is tyndall effect? Explain with an example.
उत्तर
The phenomenon in which light gets scattered by the colloidal particles in its path, causing the path of light to be illuminated, is called the Tyndall effect.
Example: The scattering of light can be observed when sunlight penetrates the canopy of a forest. The tiny water droplets present in the mist around the canopy scatter the sunlight in its path. This scattered light enters our eyes, enabling us to see the path of the sunlight.
