Question

What is Tyndall effect? "Tyndall effect can be observed, when sunlight passes through the canopy of dense forest." Explain, how this occurs?​

Answer 1

Answer:

When the sunlight enters the dense forest, the rays of light pass through these particles of colloids and get scattered. Due to the scattering of light, the path of the sun ray is clearly visible. This is called the 'Tyndall effect'.

Answer 2

$\huge\bf{\underline{\red{Answer:}}}$

This illumination of beam of light due to scattering on collision with certain particles is called Tyndall effect.

In dense forest, particularly in the early morning, there is fog i.e., tiny water droplets are suspended in air. These droplets are large enough to scatter beam of light. This is why Tyndall effect can be observed when sunlight passes through dense forest.
