Question

why do we see mirage (fake water) on road??​

Answer 1

Answer:

In the case of the “water on the road,” because the air directly above the road is hotter, it causes light rays from the sky to bend and wind up aiming at your pupils. Thus, you can't see the road ahead and instead see wavy splotches of reflective surface instead — what would normally look like pools of water.

Answer 2

Answer:

The fake puddles of water that we see on the road on a sunny day is due to an optical phenomenon called a mirage, which is caused by the refraction (or bending) of light rays due to differing temperatures of the air above the road.
