Therefore, rays coming from the top of the object will arrive lower than those from the bottom. Light rays coming from a particular distant object all travel through nearly the same layers of air, and all are refracted at about the same angle.

The mirage causes the observer to see a bright and bluish patch on the ground. The real object in an inferior mirage is the (blue) sky or any distant (therefore bluish) object in that same direction. In an inferior mirage, the mirage image appears below the real object. For example, inferior images on land are very easily mistaken for the reflections from a small body of water.Īn inferior mirage seen in the Mojave Desert in a Nevada spring
What the image appears to represent, however, is determined by the interpretive faculties of the human mind. 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. 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.
The word comes to English via the French (se) mirer, from the Latin mirari, meaning "to look at, to wonder at". Ī mirage is a naturally-occurring optical phenomenon in which light rays bend via refraction to produce a displaced image of distant objects or the sky.
