Question

Can anyone please explain the concept of mirage ?​

Answer 1

Answer:

A 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. The word comes to English via the French mirage, from the Latin mirari, meaning "to look at, to wonder at".

Answer 2

$\huge\tt{Concept \ of \ Mirage:}$

• When a light ray propagates, from a medium of high refractive index to a medium of lower refractive index, it bends away from the normal.
• At a certain [critical] angle, the refractive ray bends away so much as to just graze the boundary between the two media.
• For an angle greater than the critical angle, the ray is [totally] reflected back into the medium of higher refractive index.
• This phenomenon is known as total internal refraction.
• Optical fibres, used for transmitting and receiving [electric] signals, make use of this phenomenon.
• The phenomenon of Mirage, observed in deserts, is also due to total reflection.
• In this way, mirage forms.
