There are mainly two reasons for why air is not visible.
Its LOW DENSITY in the atmosphere is one of them. Since air has low density so its molecules are very far apart .Thus it is just Impossible to see those molecules.
The other reason is also correlated to it. Due to low density as told above the constituent molecules of air are far away from each other. We know that anything in the universe is visible only when light rays fall on them and after reflection return back to our eyes. Now the size of a molecule is of the range 10-15 and the wavelength of light rays is of the range 10-6 which is very-very large from those of a molecule. This can be thought as a cricket ball as molecule's size and the cricket stadium as the light wave.
So, the light wavelengths pass away from the molecules and never reflect back to form the image of the air molecules on our EYES.
Some times a question arises if air is compressed then air should be visible.
But this is not so, because air cannot be compressed than a certain limit.It is just hypothetical.
Air is composed mostly of transparent gases like nitrogen and oxygen. These gases do not scatter light in the visible spectrum, which is why air appears invisible to us. It is only when air contains particles like dust or water vapor that it becomes visible, such as in fog or smog.

What causes visible condensation in the air?
Visible condensation in the air is caused by a rapid cooling of the air, which brings it below its dew point temperature, causing water vapor to condense into tiny water droplets. This commonly happens when warm, moist air comes into contact with a cold surface, such as a window or a cold drink.
Why is steam visible?
Steam is visible because it consists of tiny water droplets or ice crystals that scatter light, making it visible to our eyes. When hot water vapor cools and condenses into liquid droplets in the air, it forms the visible white cloud that we see as steam.
Is air a transparent material?
Air itself is not a material; it is a mixture of gases. However, the main component of air, nitrogen and oxygen, are both transparent to visible light. This is why we can see through air with our eyes.
What is the difference between mist and water vapor?
Mist is a collection of tiny water droplets suspended in the air and is visible to the naked eye, while water vapor is the gaseous state of water and is not visible. Mist forms when water droplets condense from water vapor in the air, typically when warm, moist air cools rapidly.
Why we can't see air?
We can't see air because it is a transparent gas. Our eyes can only detect light that has been reflected or scattered by the particles in the air, such as dust, water vapor, or pollutants. Since air particles are smaller than the wavelengths of visible light, they do not scatter or absorb light in a way that is visible to the human eye.
Can air pollution be visible?
Yes such as smog
Is air something?
Yes air is something air is a visible gas its something u breath into ur nose
Can someone farts be visible in cold weather?
Yes, it is possible for someone's fart to be visible in cold weather due to the condensation of water vapor in the breath. When the warm air from a fart meets the cold air outside, it can create a visible cloud.
Why human breathe is visible in winter not summer?
The moisture in our breath condenses into visible droplets when the air is cold. In winter, the cold air causes this moisture to condense quickly, making it visible. In summer, the warmer air can hold more moisture, so our breath dissipates quickly without condensing into visible droplets.
Are light rays visible in air?
not unless it is really dusty
What is the definition for hidden line?
it is a line that is not visible but it is there it is like air
Why water vapor not visible?
because it is in the air so it is invisible
What are the three parts of the earth that are visible from space?
Sea,Land,Air
What is the biggest Formula 1 track visible from air?
Currently the belgium track

Substances discharged into the air are called what?
A substance discharged into the air
What does the fact that clean air is colorless say about its ability to absorb light?
Clean air being colorless indicates that it does not absorb visible light in the same way colored substances do. This means that visible light can pass through air without being absorbed or scattered by its molecules.
