How do you think that a mirage appears over Hainan, and how is it formed?

Mirages have existed in people's world since ancient times. Of course, in ancient times, people thought that a mirage was a very magical existence, just like a fairy descending to earth, so people at that time thought that a mirage was a place where immortals lived. People think that this is because the gods have been guarding mankind. However, with the development of modern technology and the progress of science and technology, people have gradually broken this conjecture. From a scientific point of view, a mirage is a projection produced by light refraction, and it is not a place where immortals descend to earth or live.

1. A mirage appeared in Haikou, Hainan, China, which shocked many residents, because there are high-rise buildings and buildings everywhere in Haikou, Hainan. However, this time, an ancient building appeared in a mirage. Is this a projection of a parallel world, or a mirage that has passed through thousands of years? But in fact, Shanghai's mirage is not only a reflection of the surrounding phenomena, but also a reflection of distant buildings, so it is not an ancient mirage, but an ordinary natural phenomenon.

second, according to the research of modern scientists on mirage, mirage usually does not appear in cities, and most of them appear in deserts. It's really strange to see a mirage in the city. If you see a mirage in the desert, it is common, because the temperature difference between day and night in the desert is relatively large, and the probability of a mirage is relatively high. Usually, when people walk in the desert, they will see a shadow in front. When they walked, they found that they could not reach the oasis. Gradually, people will be confused by a mirage and lost in the desert forever, so it is very dangerous to meet a mirage in the desert.

third, a mirage, also known as a mirage, is a natural phenomenon caused by the refraction and total reflection of light. When light propagates in a medium with uniform density, it will travel in a straight line at the same speed and direction. But when the light obliquely enters another medium, its propagation direction will change, which makes the light deflect at the junction of different media and appear in another space. In this way, a mirage came into being.
