Article Summary   by:roseta

The Mirage optical illusion caused by refraction of light and radiation passing through the layers of the atmosphere density interchangeable in appropriate cases and when the very hot Sahara, sun sharp cool air quickly with the dawn has broken on the ground and with this cold, fast-increasing intensity and energy to break the light.

 This is unlike some of the sun down from the upper part of the body, such as a tower of some of these rays pass on the cold air in a straight line and reach the eye of the observer without being broken so that the image appears direct to the tower to the observer but part of the light enters the hot air near the ground and moving in curve basement before turning to the top so that when it reaches the eye of the observer creates the illusion that stems from what is under the hot air, and is the heart's phantom so that it appears that the observer sees the tower Besorth flipped in the water and because the light coming from a blue sky, the impact Alsrabi can make the horizon itself appears blue and Maia, giving the illusion of a pond or along the sea.

 In colder climates and at night the desert or on the water effect will be reversed in this case gather cold air in the layer close to the ground and in order to keep warm air in the layer above it, allowing reorientation of radiation of light to the top is curved just before it fell towards the eye of the observer, as a result so you may see here the observer objects or things are not usually part of a plan under visual horizon like a ship floating in the sky called the spectrum of this phenomenon is unclear.
