You are watching: Why can t we see air
Air doesn't absorb/refract visible light exceptionally much (usually). The molecules are too far acomponent bereason it's gaseous and also they are smaller sized than the wavelengths of light anyways.
You can view air, actually. Air is a mixture of a lot of gasses, however importantly oxygen and nitrogen. Oxygen is typically classified as a colorless gas, but this isn't totally true. Oxygen atoms actually scatter a bit of the blue light wavesize, yet just barely. Due to the fact that this scattering impact is so little, it isn't noticeable in little amounts choose in a tube or even your totality living room.
No, what you require is a vast container. A container massive enough to wbelow there's sufficient oxygen to make this blue light scattering noticeable. The skies is such a container. Due to the fact that of the huge amount of oxygen in the environment we have actually sufficient blue light scattering to give the skies it's blue color.
You can watch air, actually. Think about lasers or strong flashlight beams in a dark room. What you are perceiving is the light bouncing off of the air molecules and also in the direction of your eyes, which is the exact same means we perceive solid issue. However before, air is so much less dense than solid matter or liquid that light greatly just passes via it instead of colliding via the molecules, considering that the molecules are so spread out. You can perceive laser beams and strong flashlight beams because they are offering enough light that the amount acquiring deflected by air molecules becomes perceptible, specifically in a dark room where your pupils are dilated and also the contrast would be more noticeable.
While I am no scientist, I believe air is comprised of Oxygen, Hydrogen, and Carbon dioxide, which are all molecules. Molecules are so tiny, it would be impossible for any kind of humale (or super human) to view them. Ever. I would certainly need someone to confirm this, and steam I have no idea why we check out it.
Everything about is is consisted of of molecules, including the stuff that we can't view via.
Most gases, including the ones that consist of our setting, are largely transparent to visible light.
Steam is water in a gaseous phase, and it's actually invisible. What we see once we "see" vapor is tiny water dropallows in a liquid state. They're tiny enough that the warmth can lug them upwards.

Everything is comprised of atoms, practically all of which develop molecules (I can't think a case wbelow there is a solitary atom simply chilling in nature)... your desk, your shirt, rocks, etc... although you cannot directly view little molecules, tright here are huge ones that have the right to be viewed with progressed microscopy, and we deserve to view the properties of the little molecules. Graphite is just carbon, and it absorbs a lot light, offering it a blackish color. So yes, probably if you were talking about one single tiny molecule, you wouldn't be able to check out it through the naked eye. But that's not why air is transparent
Also, air is typically primarily Nitrogen, complied with by oxygen, and then traces of whatever else.
