Question

Conditions for a mirage to occur.​

Answer 1

$<b>Mirages happen when the ground is very hot and the air is cool. The hot ground warms a layer of air just above the ground. When the light moves through the cold air and into the layer of hot air it is refracted (bent). A layer of very warm air near the ground refracts the light from the sky nearly into a U-shaped bend.</b>$

Answer 2

-Mirage is an optical illusion seen in deserts and hot surfaces.

-It occurs when hot air above the surface causes the light ray to bend upwards.
