How can you explain the mirages in the road when the temperature is high?

Answer 1

Mirage caused by heat dispersion.

Answer 2

A mirage is a naturally-occurring optical phenomenon, in which light rays are bent to produce a displaced image of distant objects or the sky. The word comes to English via the French mirage, from the Latin mirare, meaning 'to appear, to seem'. This is the same root as for mirror. Like a mirror, a mirage shows images of things which are elsewhere. The principal physical cause of a mirage, however, is refraction rather than reflection.

A mirage is not an optical illusion. It is a real phenomenon, and one can take photographs of it. The interpretation of the image, however, is up to the fantasy of the human mind.

Answer 3

It is called "gradient index of refraction "

What it shows:

There are various types of mirages possible, the details depending on whether the hot air is above or below the cool air and how sharp the transition is from cool to warm.

This is what happens when a dark asphalt road gets much hotter than the air around it -- the air next to it becomes hotter than the higher air and light traveling through this temperature gradient is bent so much that it appears reflected.

The shimmering water on a road's surface or the blue oasis in the desert are natural examples of blue skylight being reflected.

Answer 4

Mirage
When the ground is hot, it causes the hot air to rise. This movement causes a change in the density of the air over the hot ground. This change in density at the hot surface causes a change to the refraction/reflection index of the air close to the ground as opposed to the air a bit higher above the ground, like at the height of your eyes. When you look to the distance your line of vision is at a low angle to a reflective refractive surface. Also this active area of change is not occurring at a single point like the surface of a mirror would be. This layer has a thickness to it as well that can add additional effects from almost any direction.

A most interesting common phenomena.

Answer 5

The hot road heats the air directly above it. The heated air rises. This movement of the air causes an optical distortion (mirage).

Answer 6

well it's cos roads are wet and they vapor from sun heat,on hot day then the roads are dry you see those mirages cos the road heats a lot from sun so the air is hotter on road and it might seem like a mirage.

Answer 7

A combination of oil, grease and other vehicular fluids that gets on the pavement from our cars reflect the light of the sun.....it gets the 'shimmery' look on those hot 101 degree days of summer that makes it look like you will be driving into a body of water about a half mile down the road.

Answer 8

Light from the horizon hits the road surface at a low angle, and reflects off. Basically, the road acts as a mirror, and you're seeing they sky's reflection.

Answer 9

thats just heat rising you can see it on anything under the sun if you look at the rite angle

Answer 10

it's the heat coming off the pavement
