Why do things look wavy in the heat?

wavy lines that appear above the hot grill or asphalt road in the middle of summer are caused by a phenomenon called quarry. The refraction is the bending of light waves and occurs when light passes between substances with different refractive indices - in this case cold air and hot air. Because hot air is less thick than cold air, the light accelerates when it reaches a hot surface and then curls back upwards, causing the viewer to see the sky image and the surface appears. This phenomenon is responsible for desert miracles, because quarry and reflection look very similar to the human eye, and the refractive image of the sky from very hot sand may look like a reflection of the sky in the water.

The reason why things look undulating in heat, instead of appearing as a stable image of the sky, is that the air temperature is not stable. Hot air is rising, so as air comes from a hot surface, a little bitrises before it cools down quickly and sinks to be heated again. This constant mixing of hot and cold air produces vibrations, which is reflected in the refracture that looks wavy. The path that looks wavy in the heat may be dangerous because it may seem that water or oil has been spilled on the road, so it is important to manage carefully when it is hot enough to make the so -called "highway miracles" appear. The sand in the desert is also susceptible to Mirage, which thirsty passengers can interpret as an oasis.

When things look wavy in the heat, the phenomenon is known as the lower miracle , because the observed image in this case is lower or lower than a real object. It is also possible and Superior Mirage in which the image appears above the real object. For this type of miracle, hot air must be higher in the atmosphere than cold air. An example of a superior miracle is a tslunny light that is sometimes seen above the horizon when the sun itself is under hOrizon.
