On very hot days why do some dry roads appear wet and seem to reflect images?

Answer 1

On very hot days why do some dry roads appear wet and seem to reflect images due to a mirage. This is caused by light rays being bent and then produces a displaced image of the sky or distant objects.

Answer 2

This phenomenon is called a mirage, which occurs when the hot air above the road bends the light rays, creating an optical illusion that makes it look like there is water on the road. The bending of light creates a reflection of the sky or surrounding objects, giving the appearance of wetness.

Answer 4

In hot weather, roads appear wet because of a phenomenon called diffraction. The air close to a hot road has a different index of refraction that the cooler air above it. When light passes through 2 media of differing indices of refraction, the light will bend. This bending of light is called refraction, and from a distance this bent light makes it appear that the road is wet.
