Answer 1

When sunlight passes through the window of a classroom, its path is visible.

This is due to scattering of light.

Due to Tyndall effect the particles colloid and the path of light gets illuminated.

The tiny particles scatter and the beam of light make the path visible.

Through the window of the classroom, the dust particles in the air of the particular classroom scatter the beam of light all around the room.

Tyndall effect can be observed when sunlight passes through a canopy of dense forest too.
