Question

What is a mirage and what are it's conditions?

Answer 1

Near the hot ground on a summer day, particularly in the desert area,air very near the ground becomes extremely hot and light, while air considerably above the ground remains dense.Light rays coming from a distant object towards the ground are continuously refracted away from the normal and undergo total internal  reflection and the image of the object appears to come  to the observer as if after reflection from a water surface.This optical illusion is known as the mirage.

Answer 2

A mirage is like a image say like you are driving home then you see water up ahead but thats not really water as you get closer it goes way thats a mirage

Answer 3

A mirage is a naturally-occurring optical phenomenon, in which light rays are bent to produce a displaced image of distant objects or the sky. The word comes to English via the French mirage, from the Latin mirare, meaning 'to appear, to seem'. This is the same root as for mirror. Like a mirror, a mirage shows images of things which are elsewhere. The principal physical cause of a mirage, however, is refraction rather than reflection. A mirage is an example of a literal optical illusion
