Mystery of mirages
Earlier this month on a Sunday afternoon, a giant “ancient city” appeared on the surface of Hongze Lake in Jiangsu province. But after about half an hour, the “city” was gone.
You might think that some unknown forces were at work, but it’s believed that the “city on the lake” was actually a mirage.
A mirage is a trick that light and air play with bur vision(视觉). Normally, light travels in a straight line, but it can bend(弯曲)and change direction depending on what it passes through. This bending is called "refraction (折射)”.
If different layers(层)of air are at different temperatures, light will bend at different angles(角度)when passing through them. This can create a false image(影像)of a nearby object.
Take the “city on the lake” as an example. The layer of air near the lake is colder than the higher layers, as the lake absorbs(吸收)most of the heat. The buildings in the mirage were actually on a nearby mountain. But their image showed up above the lake after light refracted in different layers of air.
Mirages happen not only over large bodies of water, but anywhere where the ground can absorb a lot of heat. They are often seen on hot roads and in deserts. The next time you think you see a pool of water on the road on a hot summer day, you will know it's just a mirage—an image of the sky caused by bending light.
