Why cannot one see through fog clearly?

Verified Answer

One cannot see through fog clearly due to the scattering of light by tiny water droplets present in the air.

Explanation:

  • Fog consists of very small water droplets suspended in the atmosphere.
  • When light passes through fog, it gets scattered in different directions.
  • This scattering reduces the intensity of light reaching the eyes, making objects appear blurred or unclear.

Type of Scattering:

  • Mainly Mie scattering, which occurs when the particles (water droplets) are comparable in size to the wavelength of visible light.

Effects on Visibility:

  • Reduced contrast between objects and background
  • Blurred outlines of objects
  • Difficulty in judging distance

Real-Life Impact:

  • Causes poor visibility while driving
  • Affects air and rail transportation
  • Increases chances of accidents

Conclusion:
Fog limits visibility because it scatters light in multiple directions, preventing clear vision of objects at a distance.
