Mirage is an optical illusion that makes distant objects appear closer than they actually are. Mirages are caused by the bending of light as it passes through layers of air of different temperatures. The most common type of mirage is the inferior mirage, which makes objects appear below their actual position. This type of mirage is often seen on hot days, when the air near the ground is much hotter than the air higher up.
Mirages can be a hazard to drivers, especially on long stretches of road. Drivers may see mirages of water on the road ahead, which can lead them to drive faster than they should. Mirages can also make objects appear closer than they actually are, which can lead to accidents.
