In the desert a mirage is a what?
Correct answer: Reflection of the sky on the sand
Tom
It is not caused by reflection off the sand.
It is caused the diffraction of hotter layers of air close to the ground.
The optical density of air reduces in hotter air, causing diffraction.
Like light passing into water, or the reverse.
