The Mystery behind the Mist… Why can’t we see through fog?

Today morning when I opened the door of my sweet home and there spouted the fresh outside air towards me making me more enthusiastic. My cheeks felt cold.  As I stepped out of the house I could feel the nature associating with me. I was all set for a walk, the chirping birds singing of peace relieved my ears, when I continued further I was lost it was just like a fantasy world I could not see further I just kept moving and I felt as if I was in the same place as before. It was the haze. I actually had reached far away from my home but the fog had obstructed my vision. This made me think deep what the reason behind it.
These days morning we could see fog in our surroundings. When fog falls out in our surrounding area we see a visually perceive a whiteout in lieu of being able to make out the things.
How does fog form?
Fog consists of visible cloud water droplets or ice crystals suspended in the air at or near the Earth’s surface. Fog is fundamentally a cloud on the ground. These clouds are the collection of tiny water droplets formed when evaporated water is cooled. The infrared cooling is responsible for the fog formation
Fog normally occurs at a relative humidity near 100%. This occurs from either added moisture in the air or falling ambient air temperature. However, fog can form at lower humidities, and can sometimes fail to form with relative humidity at 100%. At 100% relative humidity, the air cannot hold additional moisture, thus, the air will become supersaturated if additional moisture is added.


Why can’t we see through fog?
It is due to scattering of light the small water droplet present in the air block the light from reaching to our eye hence we can only see through small distances.


Fog and smoke are made of particles of water, or hydrocarbons, as well as the usual atmospheric gases. These particles scatter light rays. The fog has a certain density, and there will always be a certain amount of particles between you and the object you’re looking at. You can see past or around one or two little fog particles because they are tiny. The further away something is, the more particles are going to be between you and the more they will obscure vision. Water droplets scatter light big time.


Because of this scattering, our eyes fail to gather any useful information out of this. That is the reason we can’t look through the fog.
