Determine whether true or false.

The path of a beam of light passing through a true solution is visible.

The path of a beam of light passing through a true solution is not visible. Its path becomes visible through a colloidal solution where the size of the particles is relatively larger.

Tyndall effect refers to the phenomenon by which colloidal particles scatter light. When light passes through a colloid, it is scattered by the larger colloidal particles, causing the beam to become visible.
