Question

Почему воздух не красится? Почему он всегда прозрачный?Почему он не может быть синим, например.​

Answer 1

Ответ:

Воздух невидим по причине того, что он состоит из смеси газов, без каких-либо примесей, поэтому он не отражает радиоволны и свет.

Answer 2

Why is air not colored? Why is it always transparent? Why can't it be blue, for example?

Air is not colored and appears transparent to our eyes because of its molecular composition and the way it interacts with light. The color of an object is determined by the way it absorbs and reflects light. When light passes through a substance, such as air, it can be absorbed or scattered by the molecules present in that substance.

In the case of air, the molecules that make up the atmosphere, primarily nitrogen and oxygen, do not absorb or scatter visible light in a way that produces a noticeable color. Instead, they allow light to pass through them relatively unimpeded, resulting in the appearance of transparency. This means that when light passes through the air, it is not significantly altered or absorbed, allowing us to see through it.

The reason why air cannot appear blue, for example, is due to the way light interacts with the molecules in the atmosphere. The Earth's atmosphere scatters sunlight in all directions, but it scatters shorter blue and violet wavelengths of light more than longer red and yellow wavelengths. This phenomenon, known as Rayleigh scattering, is responsible for the blue color of the sky during the day. However, the scattering of light by the atmosphere does not significantly affect the transparency of air itself.

In summary, air appears transparent because its molecular composition does not absorb or scatter visible light in a way that produces a noticeable color. The molecules in the atmosphere allow light to pass through them relatively unimpeded, resulting in the perception of transparency. The blue color of the sky is a separate phenomenon caused by the scattering of sunlight by the Earth's atmosphere, not by the air itself.
