Why is air invisible?

Answer 1

There are two reasons:

1 Air molecules are smaller than the wavelength of visible light. If a molecule or even a small particle is smaller than the the wavelngth of light, that object is "invisible". Light cannot interact with things that are smaller than the light's wavelength.

2. The air molecules can absorb some colors from white light, but not enough to create an effect. What I mean is, molecules of oxygen do absorb some specific wavelengths as the electrons in oxygen jump up and down, but these missing wavelegths are too narrow to make an effect. This is called the "absorption spectrum"

Another example: Even though Neon gives off and absorbs red light, the pure gas is clear because the aborption of red is too specific to matter.

Answer 2

Air is invisible (at the atmospheric pressure) since the molecules of gases do very weakly interact with visible light)
This means that air does not stop the visible light
If air would be visble, the atmposphere would stop the light from the sun

Answer 3

Air insists of matter. But this matter is gaseous and strong diffused so you can look 'through' it. But glass is also invisible and has a compact structure. You can look through both because of the effect that the light is completely going through the matter. Otherwise it would have another color or it is intransparent.

Answer 4

Hi. Air, like water and glass, is visible but nearly transparent in thin layers. Thicker layer become easily visible.

Answer 5

I am not sure but I think it is because the air molecules are very very very small, they also reflect almost no light and their refraction is very less.

Answer 6

cuz it is.........
