$\Large\bold\star\underline{\underline\textbf{Mirage effect\:}}$

→ Mirage is an optical illusion of water observed in deserts when the inverted image of an object say a tree is observed along with the object itself on a hot day.

$\Large\bold\star\underline{\underline\textbf{Example\:}}$

→ Check the attachment first.

→ On a hot summer day, temperature of air near the surface of earth is maximum. Therefore, density of the air close to the surface of the earth is very small.

→ As we go higher, temperature of the atmosphere decrease.
→ Therefore, the value of density of air at higher altitude above a few metres from the surface of the earth is large.

→ A ray of light from the top O' of a tree goes from denser to rarer medium. At a particular layer, when angle of incidence becomes greater than critical angle , then total internal reflection occurs and the totally reflected rays reach the observer along AE. This ray AE appears to come from I, the mirror image of "O'.

→ Thus, the inverted image of a tree creates the impression of reflection from a pond of water.
