Why do we see a sky that is empty but blue?

When we look up at the sky, we often find that there is nothing in the sky except a piece of blue, so at this time, we think,Why do we see a sky that is empty but blue? In fact, it is because the sun's rays collide with some microscopic particles in the atmosphere to produce blue light with a short wavelength, and the atmosphere is originally white, and the appearance of blue light will make the atmosphere look blue, so we will see that the sky is blue.

In fact, all objects on the earth are colorless, and sunlight is also colorless, and in our vision, we will see that many objects are colored, and sunlight is red, that is because when sunlight enters the earth, it will collide with many microscopic particles on the earth to produce light, and these lights produce light with different wavelengths because of the different degrees of collision, and blue light comes from this, and the wavelength of blue light is relatively short, and the light with a shorter wavelength is lighter. Most of it will belong to the sky, so that's why we often see the empty sky, which is blue.

For example, the plants that can be seen everywhere in our lives, under normal circumstances, plants are green, but after scientific research, it is found that the plants themselves are not green, and the reason why we see plants are green is because there are chlorophyll and other substances in the plant, and when the sunlight hits the plant, the plant will reflect the color of chlorophyll, and this is why we will see that the plant is green.

Like plants, the sky is white at first, and because the sunlight collides with some examples in the atmosphere, resulting in a shorter wavelength of blue light, which is reflected by the atmosphere to the atmosphere so that in the eyes of astronauts entering the atmosphere, the atmosphere is white, and in the eyes of people on Earth, it is a piece of blue, so that's why there is nothing in the sky, but the sky is blue.

This is because the sun's rays collide with some microscopic particles in the atmosphere, resulting in a shorter wavelength of blue light, which is otherwise colorless. The appearance of blue light makes the atmosphere appear blue, so we will see that the sky is blue.

The blue sky we see is because of the scattering of sunlight by the atmosphere, which allows us to see a blue sky.

The atmosphere scatters sunlight into blue. Sunlight shines on the atmosphere, and the atmosphere is constantly refracted to form a blue color.

Because the sky reflects the color of the ocean and the white clouds reflect the sun's rays, the sky is blue and the clouds are white.

That's because the sky and the white clouds are two different substances, and secondly, some of the water in the white clouds and other substances are thicker.

The iron pot itself has no color, when the sunlight shines on the molecules of the atmosphere, the substance of water droplets, when the sunlight refracts some color through the earth and the moonlight enters the atmosphere, if the wavelength is short, it will be refracted blue, if the wavelength is long, the cabinet hole will be bent red, which is why the sky we see during the day is blue, and the sky we see in the evening is red.

Because of the presence of air molecules and particles in the sky, macros scatter the visible light in the sunlight, and the blue light emitted by the dust in the atmosphere exceeds the energy of other photons.

Because of the atmosphere of the Zen skin, when the sun's light passes through the atmosphere, it will be emitted and scattered, and the atmosphere contains many substances, so the agitation difference will cause the lead ant to appear blue.

Extended information: The sky has a variety of manifestations, it is carrying the light that is the fastest in human understanding, and it is the most primitive creative enlightener of human beings.

The various forms are usually expressed in terms of weather, and weather noise refers to the specific state of the atmosphere in a certain place close to the earth's surface in a short period of time. Weather phenomena refer to various natural phenomena that occur in the atmosphere, that is, the comprehensive performance of the spatial distribution of various meteorological elements in the atmosphere (such as temperature, air pressure, humidity, wind, clouds, fog, rain, flash, snow, frost, thunder, hail, haze, etc.) in a certain instant. Weather processes are the process of changing weather phenomena in a certain area over time.

All kinds of weather systems have certain spatial and temporal scales, and the various scale systems are intertwined and interact with each other. The combination of many weather systems constitutes a large-scale weather situation that constitutes the atmospheric circulation of the hemisphere or even the world. Weather systems are always in the process of rebirth, development and disappearance, and have their corresponding distribution of weather phenomena at different stages of development.

Because the Earth's atmosphere absorbs light from other colors and retains its blue color, the sky we see is blue.

The sun has many colors of light, and the color of the sky we see is formed after many refractions. Among them, the blue band of sunlight has the largest energy. So in the end we see that the color of the sky is blue.

When light enters the atmosphere, it reacts with the particles inside, and the blue light inside is scattered, and the sky turns blue.
