Mirage : An optical illusion - What is a Mirage and Why do we see a Mirage
A mirage is a naturally occurring optical phenomenon in which light rays bend to produce a For exhausted travelers in the desert, an inferior mirage may appear to be a lake of water in the distance. An inferior by jet engines. When appearing on roads due to the hot asphalt, it is often referred to as a highway mirage.
What causes a mirage?
Imagine you're in the desert. You're lost. You've been walking for hours. You've run out of water. On the horizon, you see a giant, shimmering puddle of water.
A mirage is a naturally occurring optical phenomenon in which light rays bend to produce a displaced image of distant objects or the sky. The word comes to English via the French mirage , from the Latin mirari , meaning "to look at, to wonder at". This is the same root as for " mirror " and "to admire". Mirages can be categorized as "inferior" meaning lower , "superior" meaning higher and " Fata Morgana ", one kind of superior mirage consisting of a series of unusually elaborate, vertically stacked images, which form one rapidly changing mirage. In contrast to a hallucination , a mirage is a real optical phenomenon that can be captured on camera, since light rays are actually refracted to form the false image at the observer's location. What the image appears to represent, however, is determined by the interpretive faculties of the human mind.
To understand how a mirage forms, one must first understand how light travels through air. If the air is all the same temperature--cold or hot--light travels through it in a straight line. If a steady temperature gradient exists, however, light will follow a curved path toward the cooler air. The standard freshman physics explanation for this phenomenon is that cold air has a higher index of refraction than warm air does. As a result, photons particles of light travel through hot air faster than they can through cold air because the hot air is less dense.

What is a mirage? How is it formed? The angle of incidence i is smaller than the angle of refraction r. A traveler has lost his way in the desert. Enduring thirst and hunger, he suddenly saw an oasis, so the overjoyed man quickly ran towards it. To his great disappointment, it was just an illusion produced by a mirage. Such an episode was often pictured in movies, yet the optical magic that the nature plays with us - mirage - really exists in reality.
Mirage , in optics , the deceptive appearance of a distant object or objects caused by the bending of light rays refraction in layers of air of varying density. Under certain conditions, such as over a stretch of pavement or desert air heated by intense sunshine, the air rapidly cools with elevation and therefore increases in density and refractive power. Sunlight reflected downward from the upper portion of an object—for example, the top of a camel in the desert—will be directed through the cool air in the normal way. A direct image of the camel is seen also because some of the reflected rays enter the eye in a straight line without being refracted. The double image seems to be that of the camel and its upside-down reflection in water.
