### Short Note on Tyndall Effect

The Tyndall Effect is a phenomenon observed when a beam of light passes through a colloidal solution. In such solutions, the size of the dispersed particles is comparable to the wavelength of the light. When light encounters these particles, it gets scattered, making the path of the light beam visible.

This effect is commonly observed in everyday life. For example, when sunlight passes through a misty or foggy atmosphere, the light is scattered by the tiny water droplets, allowing us to see the beam of light. Similarly, in a colloidal solution like milk, the light is scattered due to the presence of fat globules, making the path of light visible. In contrast, a true solution, such as sugar dissolved in water, does not exhibit the Tyndall Effect because the solute particles are too small to scatter light.

In summary, the Tyndall Effect is significant in distinguishing between colloidal solutions and true solutions based on their ability to scatter light.
