Is the Shuifurong Hotel really a mirage?

Mirage, also known as mirage, is a natural phenomenon caused by refraction and total reflection of light. It is a virtual image formed by the refraction of light reflected by objects on earth through the atmosphere, and its essence is an optical phenomenon. The appearance of mirage is closely related to the geographical location, geophysical conditions and meteorological characteristics of those places at a specific time, which is manifested in the repeated appearance and simultaneous appearance of the same place.

In calm seas, rivers, lakes, snowfields, deserts or Gobi, occasionally towering towers, city walls and trees appear in the air or "underground", which is called a mirage. This illusion often appears on the sea surface of Penglai, China. The ancients attributed it to the dragon, exhaling and forming the tower wall, hence the name. Hot air rising on sandy or stony surfaces refracts light, and a mirage is formed.

Mirages will appear in desert areas about 6 miles (9.6 kilometers) away from the coastline, which will make objects outside 1 mile (1.6 kilometers) or farther seem to be moving. This makes land navigation very difficult, because in a mirage environment, natural features are vague. A mirage will make it difficult for a person to distinguish distant objects, and it will also blur the outline of distant vision. You feel like you are surrounded by a piece of water, and the rising part of that area looks like an "island" in the water.

Phantom will also make it difficult for you to identify the target, estimate the range and find someone. But if you go to a higher place, which is 10 feet (about 3 meters) higher than the desert ground, you can avoid the hot air near the surface, thus overcoming the mirage. In short, as long as the height of the wait-and-see is slightly adjusted, the mirage phenomenon will disappear, or its appearance and height will change.

Mirages often appear in the sea and desert. Mirage is the result of light refraction along a straight line in gas layers with different densities. There are many kinds of mirage: according to its position relative to the original, it can be divided into three types: upper, lower and side; According to its symmetrical relationship with the original object, it can be divided into positive, lateral, positive and negative; According to the color, it can be divided into colored mirage and colorless mirage.
