When a car is moving through a dusty road during night a path of beam from the headlight is clearly visible due to ________ effect.

Correct option is A

The correct answer is (A) scattering.

• When dust particles are distributed across the air, the air gets suspended.
• The light is then scattered, allowing the path to be seen.
• Scattering of light- Light can be examined completely from its source.
• When light travels from one medium to another, such as air or a glass of water, some of it is absorbed by medium particles, followed by subsequent radiation in a specific direction.
• This is referred to as light scattering.
• The intensity of scattered light is determined by particle size and light wavelength.
