About Mirage

The best answer is actually a self-justifying explanation that cannot be explained by modern science. A mirage is a true manifestation of another dimension. Under the movement of matter, it is reflected in our space. In addition, the mirage scenes that people see are sometimes in motion, and the matter in other dimensions is also in motion. In deserts or other places, if matter can form a huge microscopic observation system under motion, people can observe other spaces, which is what people call mirages.

This is purely an expression of provocation!

How to explain the cause of mirage? The two situations and two statements mentioned in the title are, to put it bluntly, the same thing, a natural phenomenon that occurs due to the refraction of light.

There are three types of mirages, namely upper mirage, lower mirage and side mirage. In coastal cities, due to the high humidity and density of sea air, when light enters the eye, the optical path is from an optically sparse medium to an optically dense medium. As mentioned in junior high school physics, in this case, due to human visual habits, The tangential extension of this curve (due to the change in density of the medium, the light does not propagate in a straight line at this time, but is an arc, and it is in the same bending direction as the earth's surface) near the eye, gives the impression that the scenery appears in It fills the sky, giving people the feeling of wonderland.

In fact, the sunrise is also like this, but in meteorology this is called a mist, and it is also a mirage. When we see the sunrise for the first time, the sun is actually still below the horizon. This is the effect of the continuous refraction of light in the atmosphere. Therefore, we cannot see the so-called "Midnight Island" on the earth because of the poor fog. , there is no obvious dividing line between day and night on the earth. This theoretical dividing line is refracted by the atmosphere to form the dawn, which is the appearance of dawn.

The mirage is in the desert. In the desert, due to the long-wave radiation from the ground (infrared heating, like a microwave oven), you can feel it when walking barefoot on the beach at noon in summer. The temperature of the ground is very high. high. At this time, the air near the ground is heated, and its density is actually less than the air above, and convection is formed. Li Shangyin said, "The sun is warm in Lantian, and the jade produces smoke." This is what he is talking about. The light refracted at this time, and the direction of the light path is curved. It is different from the curvature direction of the earth's surface. If the light path of the upper mirage and the surface of the earth are concentric circles, which implies a relationship; then the lower mirage is two arcs that are tangent or separated from each other (of course, this is an example, many times the light path is not a circle , are other types of curves, but the direction of their curvature is as mentioned above)

The mirage is not in the sky, but close to the ground, and is opposite to the actual situation. Just like the reflection in the water, people walking in the desert often think they see an oasis or a source of water, but in fact in many cases it is a mirage. . .

The causes of sideways mirages are also similar, but they are a bit "weird" compared to the previous two situations. After all, people feel a little mysterious when they see things behind them.
