A mirage is a beautiful phenomenon. If you understand the nature and its concerning physics hidden in the mirage, you will undoubtedly be left with your mouth open wide in awe and admiration. To be way more precise, a mirage is an optical phenomenon.

A mirage is formed when a ray of light or a beam of light bend to produce a displaced image of objects that are far away or the blue sky. It appears as if there is a pool of water on the road but when one gets near it, we witness that the road is in actuality purely dry and the pool of water down here was nothing more but just an illusion.

The word "mirage" is derived from the Latin word "mirrare" which means "to seem or appear". The root cause of a mirage forming is the bending of light that is refraction and not reflection. You may find id highly fascinating that one can easily and without any sort of difficulty take and capture a photograph of a mirage! There exist three kinds of mirages:-
1. inferior mirage
2. sunset mirage
3. superior mirage

A mirage is a reflection or image caused by light rays undergoing total internal reflection. The condition necessary for producing a mirage is a layer of hot air lying just above the ground with another layer of cooler air immediately above it. because the cool air is denser than hot air, light travels more slowly in cool air than in hot air.

Thus, as light rays travel from cool layer to the hot layer they are refracted at the boundary at angles greater than the critical angle, and total internal reflection takes place. For example, light rays from a distant tree are refracted as they pass downstairs from cool to the hot layers. Some of the light rays from the tree are incident on the boundary of the hot and cool air layers at angles greater than the critical angle. These rays are totally internally reflected upwards and eventually reach the eye of a person. They appear to come from a place on the ground very much closer that is the eye only sees an image of the tree.
