• A. scattering of light
• B. refraction of light
• C. dispersion of light
• D. reflection of light

Answer 1

Answer:

A. scattering of light

Read Explanation:

Scattering of light occurs when particles in the air (smoke particles in this case) redirect the beam in various directions, making the light visible to the eye. The Tyndall effect is the scattering of light by particles in a colloidal suspension, making the path of the light visible. It can be observed in examples such as sunlight passing through a dusty room, fog, or a mixture of milk and water
