Unequal heating of different layers of atmosphere causes different temperature for different layers and as a result different densities which further adds that the speed of light will be different in these layers (layers will be having different refractive index) ie, white going higher from the surface the refractive index decreases and the layers becomes rearer and light ray going up from surface after passing each layer of atmosphere bends away from normal (because it passes from denser to rearer medium) and at a particular angle it suffers total internal reflection and comes back to the surface and falls on a person eye (this is called a mirage).

Because of the refraction of light.

Light travels from denser to rarer medium.

A mirage is a pool of water ahead of a traveler on a hot sunny day and it is as a result of total internal. It disappears as the traveler approaches it.

It is because total internal refraction.

It is a phenomenon caused in the atom.

The Above Phenomenon is a great example of TOTAL INTERNAL REFLACTION, Which comes in account when light travels from denser medium to rearer medium, after some specific angle it again reflacts into the denser medium. Similar kind of activity happens in desert area called "Mirage" or "Marichica".

It is due to the total internal reflection that the ray refracts from denser to rarer.

What is mirage tree?

It is due to total internal reflection.
