What caused the formation of a mirage?
The reasons for the formation of 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 layer of particles, it is invisible to the human eye, let alone the space of smaller particles composed of 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 mirage of miaodao islands in Bohai Sea, which is called? Phantom? Known as.
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.
The meaning of dreaming of a mirage
A mirage represents an unreal and unreal scene. A mirage in your dream expresses your imagination and expectation. The sea is vast, profound and has a sense of belonging. Everyone has different feelings about the sea, and the deeper meaning needs to be judged by your own feelings about the sea. Fauna is the humanity you want to feel in reality. Lions and beasts are stronger. It is not directly related to business trip, but reflects some feelings about husband and wife's life.
Dreaming of a mirage: there will be chaos in residential areas
Young people's dreams are a mirage, which will affect your health: the focus is still on your heart, and you should pay attention to the peace of mind. In addition, there may be dyskinesia or spasm.
Unmarried people dream of a mirage, so love fortune: the key word of love is communication, and there are more opportunities for couples to chat, discuss and even quarrel, which may be regarded as a process of mutual understanding. At the same time, I often talk about new love.
Other magical natural phenomena in China.
The world is full of miracles. Have you ever seen a place where winter and summer are upside down? Have you ever seen the sun all day? Three ups and downs? Where do you live? Have you ever seen a strange place where it can call the wind and rain? Have you ever seen a canyon with four seasons like spring? Some of these incredible phenomena can't even be explained by scientists. Let's go to China and see those magical places together!
First of all, winter and summer are reversed.
In Taihang Mountain, northwest of slate in Linxian County, Henan Province, there is a place with an altitude of1500m. In winter, the water temperature is warm and smoky. In summer, Shui Han is very cold, and the north wind blows clothes. The ice here began to freeze in the spring of March and the ice age lasted for five months. In the cold winter, the hot air is steaming, and the spring water overflowing from the rocks is warm and pleasant. There are often strange flowers and grasses on the banks of the stream, which are bright and green. Many scholars continue to explore and study this, but so far this natural mystery has not been solved.
Second, the sun is a day? Three ups and downs? The position of
There is a place in Yunnan called Liming, where you can watch the sunrise and sunset three times a day. At dawn in winter, the sun is orange. As soon as the sun climbed out, it lit up the originally colorful cliffs. Strangely, the newly rising sun only stayed in the sky for about two hours, and then it went down again. When people feel sorry for the short days in this canyon, the mountains are glittering behind. Soon, a red sun set and rose, hanging in the blue sky. However, the good times did not last long. A high mountain blocked the sun and the sun set again. In this way, the strange landscape where the sun sets and rises in one day is surprising.
Third, Shenyang strange slope
There is a strange slope near Hanpoling, Yan Jia Village, Qingshuitai Town, Xinchengzi District, Shenyang. The strange slope looks low in the east and high in the west, 80 meters long and 15 meters wide. If you drive a van with more than ten people in it, you can slide uphill and stop at the top of the slope. Riding a bicycle down a slope, you can't walk without pedaling. You can only pedal hard to reach the bottom of the slope. Ride up from the bottom of the slope without pedaling, and the car will automatically slide up. According to relevant sources, it is caused by optical illusion, not the east is low and the west is high.
Fourth, the magical fragrance.
Qingshui Village, Shanmen Town, Dongkou County, Hunan Province, has a wonderful land with an area of 50 square meters, which smells fragrant all year round and makes people feel relaxed and happy. Sandalwood smells in spring and summer, and osmanthus smells in autumn and winter, but the more fragrant, the less fragrant. This wonderful fragrant soil is located in a concave place on the hillside about 2 kilometers northwest of Qingshui Village, Shanmen County, Hunan Province. This is a remote place surrounded by mountains, with cliffs above and gurgling streams below. It is said that a mountaineer who collects herbs often goes to this mountain to collect herbs. One day, a mountaineer who was collecting herbs happened to pass by here and felt a wonderful smell coming from the nose. He felt very curious. In order to find the source of the fragrance, he searched all the flowers and trees here, but to no avail. Finally, it dawned on him that the original fragrance came from the ground under his feet. This surprised him very much. Incredibly, this land exudes this wonderful fragrance.
5. Land that can forecast the weather
Shizhu Tujia Autonomous County in Sichuan Province has a land that can forecast the weather, with an area of about 10 square meter. It is a red sand bar, and its color changes with the weather. Sunny days are white, cloudy days are pale and rainy days are brown. Farmers in Qili, Fiona Fang use this as a basis for observing the weather and arranging farm work. Because the sand bar looks like a human figure from a distance, people call it? Red man? .
Sixth, this is a strange place called wind and rain.
There is a forest belt on the beach on the southwest coast of Wanning County, Hainan Province. In the early morning of early summer every year, thunder often bursts in the forest and it rains cats and dogs, but it doesn't take long for the rain to clear up, but it doesn't rain as much outside the forest. According to relevant analysis, this may be caused by regional forest microclimate.
Seven, summer frozen mountainside
On the mountainside of Baidaozhai, the highest peak in Wufeng County, Hubei Province, which is 2320 meters above sea level, there are two places with an area of about 1 000 square meters. After the midsummer, the ice melted and reappeared the next summer, which was amazing.
Eight, four seasons like spring canyon.
In Longshan county, Xiangxi, north Hunan, there is a place called? Thirty-mile gallery? Canyon, like spring all the year round, with almost no subtle changes, is called the place of constant temperature. After reading the above eight wonders, I believe many people are interested in these strange and mysterious phenomena or buildings. They are quite distinctive and impressive, attracting the curiosity of many people.
Formation conditions of mirage
Mirages are closely related to the geographical location, geophysical conditions and meteorological characteristics of those places at a specific time. The abnormal distribution of temperature is the meteorological condition for the formation of most mirage.
As far as the formation of taking down the slug is concerned. In summer, the sun shines brightly in the desert and the sand is burnt. Because of the small specific heat of sand, the temperature rises very quickly, and the sand is nearby.
The density of cold air on the mirage (2 pieces) in the desert is high, which makes the refractive index of air lower and upper. When the light reflected by a distant higher object enters the sparse air in the lower layer from the dense air in the upper layer, it is constantly refracted, and its incident angle gradually increases, which is equal to the critical angle, and total reflection occurs. At this time, if people look against the reflected light, they will see the cockroaches below.
Because of the dark color of asphalt pavement, it has strong absorption ability in the hot summer sun, and it will also form the distribution characteristics of cold and dense upper air and hot and dense lower air, so it will also form underflow.
It happened in the desert? Phantom? It is the refraction phenomenon of sunlight when it meets air with different densities. In the desert, the sand is baked by the sun during the day, and the temperature on the surface of the sand layer rises rapidly. Due to the poor heat transfer performance of air, when there is no wind, the vertical temperature difference over the desert is very significant, with high air density in the upper layer and low air density in the lower layer. When the sunlight enters the low-density air layer from the high-density air layer, the angle of the light changes, and after the refraction of the light, the oasis in the distance appears in front of people. Sometimes this happens on the sea or on the river? Phantom? Phenomenon.
A mirage is an optical illusion, a virtual image formed by the refraction of light reflected by objects on the earth through the atmosphere. Phantom is a mirage for short. According to the principle of physics, a mirage is because different air layers have different densities, and the refractive index of light in air with different densities is different. That is, because the density between the cold air on the sea surface and the warm air at high altitude is different, the light is refracted.
The principle of phantom formation
Refraction of light: When light is obliquely incident from one medium to another, its propagation direction changes, so that light is deflected at the junction of different media. Understanding: the refraction of light, like the reflection of light, occurs at the junction of two media, except that the reflected light returns to the original medium and the refracted light enters another medium. Because the propagation speed of light in two different substances is different, the propagation direction changes at the junction of two media, which is the refraction of light. [5]
