Air looks invisible because it sends very little color to our eyes. Air is a mixture of gases, mainly nitrogen and oxygen, with small molecules that are far apart. … Wavelengths of light may pass by these molecules without hitting them.
A: Air is normally invisible. From space, the atmosphere, which is made of air, looks like a thin blue band because of the way the light passes through it.
Air is colourless. The air is transparent and has no specific colour. But, when the sun shines on Earth’s atmosphere the light is bent and scattered by many particles in the atmosphere.
Given that wind is the movement of air, you cannot actually see wind, because it is simply moving air. BUT sometimes there is enough dust, or pollen, or smoke , or water vapor in the air that you can see see them, even though you can still see THRU the air as well.
Air is present all around us. We cannot see the air around us but we can feel its presence when the leaves rustle or branches sway. 1.
Air is transparent to our eyes because we have evolved retinas that are sensitive to the very wavelengths of light that pass through it unobstructed – otherwise we wouldn’t be able to see anything at all. Wind is just moving air, caused by pressure differences in the atmosphere.
You can touch air and air is touching you all the time except that the nerve receptors on your skin are not sensitised to it.
The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.Jun 6, 2018
Short answer: Mostly blue, with some green, brown and white. Long answer: There are several main colours of the planet Earth, the dominant colour being blue. This comes from the oceans and the atmosphere. Water is blue when it’s more than a few metres deep, and the oceans also reflect blue light from the atmosphere.
Liquid air is air that has been cooled to very low temperatures (cryogenic temperatures), so that it has condensed into a pale blue mobile liquid. … Liquid air can absorb heat rapidly and revert to its gaseous state.
The Short Answer:
Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.
Many animals appear to have an impressive ability to follow the wind to find food, avoid predators, and connect with potential mates. Until now, however, no study had examined how land mammals know the direction of the wind. New research finds that an important part of this ability lies in an animal’s whiskers.
The sound, propagating in the air, is really pressure differences/waves. So, you cannot hear (directly) a gentle breeze of air. However, if you have turbulent air movements, pressure differences are produced, resulting in sounds that you may hear. When we hear sound, it’s because of air molecules vibrating.
Other gases in the atmosphere (particularly oxygen, carbon dioxide and water vapour) also absorb light, but at ultraviolet and infrared wavelengths that we can’t see. … So it’s not that gases are invisible, as such, it’s just that we can’t see atmospheric gases as they don’t have a colour in the visible range.
Sometimes water is invisible when it is in the form of water vapor and water is visible in the form of water droplets. Strategy and Activities: Today, we will look for visible water in the form of water droplets and invisible water in the form of water vapor.
If we could see “air” to any significant degree — and not just the smog, water vapor, etc suspended in it at times, the — it would look BLACK as the large layer of air above us would block all of the sunlight. In such an environment, we likely would never have developed eyes even.
Earth’s gravity holds air to its surface, so we are all submerged in a “sea” of air. The weight of the air is constantly pushing against us, but it feels more like pressure than weight since it pushes from all sides. This all-around push is a force called air pressure.
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don’t technically drown, because they don’t inhale the water, but they do die from a lack of oxygen.
If there was no air on earth, plants and animals would not survive. The latter use oxygen for respiration, therefore they will not get the necessary fuel for the breakdown of the food products. … All life forms will cease to exist on the earth resulting in the planets becoming uninhabitable.
Air does reflect light. That’s how mirages come into being. Granted, this reflection takes place at relatively low angles of incidence and at a relatively sharp boundary between air layers of different temperature (and thus density and thus index of refraction), but it certainly happens.
