This Monday at dawn, on the beach of Gavà, in the Baix Llobregat, it was possible to see this spectacular postcard of the luxury cruise in the middle of the sun.
As can be seen in The Photos of the Readers of La Vanguardia, it seems that he wanted to offer his passengers a close-up of the moment of sunrise.
In this case, in addition, we can observe that the sun is deformed, a phenomenon that is due to the fact that the sun's rays are deflected when passing through the earth's atmosphere.
This is an optical phenomenon known as "refraction" and the angle that light is bent after passing through the Earth's atmosphere is known as the "angle of refraction".
Refraction is the change in direction and speed that a wave experiences when passing from one medium to another with a different refractive index. It is also very well observed with respect to the sun when, for example, the so-called Omega effect occurs.
This spectacular phenomenon is formed when the air, in contact with the surface, very dense and at the same time warmer, produces the refraction of light, which deforms the sun and creates the mirror effect, which then takes the shape of an Etruscan vase, like It was defined by the writer Jules Verne.
