Phenomenon of the Fata Morgana
Definition of fata morgana in optics: optical illusion, similar to the mirage, which occurs mostly on the surface of the sea near the coast.
In the presence of the phenomenon of fata morgana, objects appear suspended in the air, with continuously changing dimensions and shapes.
The physical explanation of the fata morgana lies in the variation in density which entails a change in the refractive index of the air near the ground caused by high variations in temperature contrast.
The Fata Morgana is an elaborate form of mirage, which can only be viewed within a narrow band above the horizon.
The name originates from the history of the Fata Morgana coming from a Celtic legend, a character with magical powers that induced in the sailors the visions of fantastic castles in the air or on the ground to distract them and attract them to death.
The phenomenon of the fata morgana, which can be seen both on land and at sea in different places in the world, makes objects distorted and therefore not recognizable to the point that the sensation is that of a rapid evolution and change of the subjects of the mirage that they compress and stretch quickly.
