Why is the sky blue? A scientific perspective is required

This is a bit cumbersome to explain.

To put it simply: the outer layer of the atmosphere is the ionosphere, and the polarization phenomenon will occur when sunlight enters it, that is, only the light in a certain polarization direction can be smoothly in, and the light in the polarization direction here is blue in the eyes of people.

That's one thing.

On the other hand. There is a certain distance between the person and the ionosphere, and there must be an angle deviation when you look up, and the farther away the polarization phenomenon occurs from the person, the greater the angle, and the more obvious the polarization in that direction, so relatively speaking, the distance looks bluer than the near one!

The ground floor is very imaginative and nice!

This problem could be written in a book, in one sentence: the reflection of sea water.

So why is the sea blue? How is this blue to low formed?

The first floor is very good.

I agree.

The blue sky is a beautiful sight of nature and a symbol of people's health and happiness. We should protect the environment and reduce pollution, and Lu Qi let Lan Wanghao always accompany us every other day.

The blue sky is a beautiful sight of nature and a symbol of people's health and happiness. We should protect the environment, reduce pollution, and let the blue sky always be with us.

As sunlight passes through the atmosphere, its shorter wavelengths of blue light are scattered more, while longer wavelengths of red light are scattered less. Therefore, when we look up at the sky, we see a blue sky.

The meaning of blue skies.

Blue sky refers to a clear and cloudless sky, which is the most common weather condition in people's daily lives. Blue skies are made up of gases and particulate matter in the atmosphere, with nitrogen, oxygen, and water vapor being the main components. The formation and meaning of blue skies have attracted much attention.

The official department has already given an explanation, so the online answer is just a strange statement, but the reasons are the same. When I say this, I don't agree with the official explanation. I think sky blue is the blue light emitted by the silver heart that is 20,000 or 30,000 light-years away, and the atmosphere is blue.

A piece of glass, which we think of as colorless and transparent, is superimposed with a sufficient number of glasses to see the color. The distance between the same substance and us is like a piece of glass, so we can't see the color of the air. And the height of the sky is like a sufficient number of glasses superimposed, so the sky is blue when seen.

There are three reasons for this: 1) the volume and mass of the silver core are infinitely larger, innumerable 、-- times larger than that of the sun, so that the temperature of the energy produced by the silver heart is higher than that of the sun, until the high produces blue light; 2) The distance of 20,000 or 30,000 light years is not to mention how many billions of planets, so that the blue light of the silver heart can only be scattered into space, so we can only see the sky blue, but we can't see the direction of the sky blue, let alone the silver heart; 3) The ocean is blue, and the ocean is thick enough to cause the ocean to resemble a sufficient number of glass superimposed, so the ocean is blue. Lakes or rivers that are not deep enough are not blue because they only resemble a single layer of glass.

Because light is composed of 7 different colors, because the light is refracted by water vapor during the irradiation process, and because the blue light has a long wavelength band, the others are absorbed, but the blue is not absorbed, so it looks like the sky is plum color with the naked eye.

This is a natural phenomenon.

If the sky is not blue.

That's the most worthy question for scientists in the world.
