what is mirrage explain the conditions under what under which it is seen

Answer 1

Sometimes, in deserts,an inverted image of a tree is seen which gives a false impression of water under the tree.This is called mirage.

The cause of mirage is the refraction of light.Formation of mirage is a result of the refraction and total internal reflection of light in the air.It is caused by a change in the refractive index due to high temperature near the surface and lower temperature above it.
