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.
