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 dense forest canopy, where tiny water droplets in the mist scatter light, showcasing the Tyndall effect in a natural environment.
Provide an example of the Tyndall effect in a natural setting and explain how it occurs.

An example of the Tyndall effect in a natural setting is seen in a forest when sunlight filters through the canopy. The sunlight interacts with airborne particles like dust, pollen, and water droplets suspended in the air. These colloidal particles scatter shorter-wavelength light, particularly the blue and violet components, making the sunlight visible as rays of light streaming through the foliage. This effect occurs due to the scattering of light by the colloidal particles, creating a visible path of light in the forest. The Tyndall effect is responsible for the enchanting and observable rays of sunlight in such settings.
