What caused the mirage?
Mirages often appear in coastal areas and occasionally can be seen in the desert. People can see houses, people, mountains, forests and other scenery, which can be moved and lifelike. Some people think it is a fairyland on earth. Now people say that a mirage is the result of atmospheric refraction, which refracts distant scenery to the nearby. In fact, this is a self-defense that modern science cannot explain.
Within the three realms, there are also many layers of material space. The nine-story heaven and eighteen-story hell mentioned in religion, such as heaven and man, ghosts and gods, are all in different spaces. We human eyes can't see them.
The light that people in our space can see is in the visible range (400-700 nm). We see matter because our eyes can receive visible light reflected by matter. At night, we can't receive the infrared rays emitted by substances. Even in the visible range, if the light is too strong or too weak, we can't see it. The human eye is composed of the largest particles composed of the substances in our space and the largest molecules, and it is only suitable for seeing light within a certain energy range.
If it is a layer of space particles, composed of molecules slightly smaller than the largest particle layer, it will not be visible to human eyes, not to mention that space particles are composed of smaller molecules. For people, the light reflected by these substances is invisible light. However, the life in this space can receive the light reflected by the matter in this space and can see the matter in this space, because the molecular particles that make up their eyes are different from those of human eyes.
A mirage is the true embodiment of another space. Under the movement of matter, it is reflected in our space. A mirage happened at sea. The air humidity here is high, and the air humidity in a certain range is relatively high and the thickness is relatively large, which makes a large area of water vapor mistakenly form a huge lens system under the movement. Just like a huge magnifying glass and microscope, it reflects the scene of another space in the microscopic world to our space. The human eye can observe it.
In addition, the mirage people see is sometimes moving, and so are the substances in space. In the desert or other places, if the material can form a huge microscopic observation system under the movement, people can observe another space, which is what people call a mirage.
Mirages often occur after rain, when the air humidity is high and it is easy to form a lens system.
When the temperature near the ground changes sharply, it will cause a huge difference in atmospheric density, and the distant scenery will undergo abnormal refraction and total reflection when the light propagates, thus causing a mirage.
Penglai County, Shandong Province, China often sees the illusion of miaodao islands in the Bohai Sea, which is called a "mirage".
Mirage is the result that the temperature near the surface layer changes greatly, the air density changes strongly with the height, and the light is refracted to the observer's eyes in the vertical gas layer with different densities. It is often divided into upward, downward and sideways mirage.
In fact, what astronauts see in space travel is an enlarged view of the earth, which is sometimes called a mirage.
