Question

Mist is fog with horizontal visibility of

• A. 100 m
• B. 200 m
• C. 500 m
• D. 1 km

Answer 1

The correct option is D 1 km

The visibility of less than 1 km is the standard range for fog, that is formed due to condensation of the water droplets near earth's surface. Mist is formed due to the dispersion of dust and smoke in the air along with nucleation of the water droplets and the visibility range for mist is between 1 km to 2 km. The visibility range for haze is between 2 km to 5 km.

Hence, the correct answer is '1 km'
