Question

on hot summer days mirage in deserts . This happens because ___.

Answer 1

here is ur answer


The phenomenon is called inferior mirage. The responsible effect is the dependence of the refractive index of air on the density of air which, in turn, depends on the temperature of the air (hot air being less dense than cold air).

On roads it may look as if water, or even oil, has been spilled. These kinds of inferior mirages are often called "desert mirages" or "highway mirages". Both sand and tarmac can become very hot when exposed to the sun, easily being more than 10°C hotter than the air one meter above, enough to create conditions suitable for the formation of the mirage.
