The Tyndall effect is observable when a fine beam of sunlight enters a smoke-filled room through a small hole. The scattered light by colloidal particles in the smoke makes the beam visible. Another example is the sunlight passing through a ...

The Earth’s atmosphere is composed of a heterogeneous mixture of minute particles, including smoke, tiny water droplets, suspended dust particles, and air molecules. When a beam of light interacts with these fine particles, its path becomes visible. The light is ...

The larger size of colloidal particles leads to enhanced scattering of light, making the path of a beam of light passing through a colloidal solution visible. In contrast, true solutions, with smaller particles, do not exhibit this visible scattering, rendering ...
