In fog, light scattering mainly happens due to what?

Answer and explanation

Correct answer: Tiny water droplets

Correct answer: A, tiny water droplets. Fog contains numerous microscopic liquid-water droplets suspended in air. When light travels through this collection of droplets, the light is redirected or scattered in many directions. This scattering reduces the amount of clear light reaching the observer from objects and therefore lowers visibility. A is correct because the droplets are the particles present in fog that interact with light. B is wrong because large stones are not floating throughout fog. C is wrong because hot lava is not a component of ordinary fog. D is wrong because dry sand is not the main suspended material responsible for normal fog scattering. The density and size of droplets, along with lighting and background conditions, affect how strongly visibility is reduced. Memory cue: fog blocks clear seeing because suspended droplets scatter light.
