I share in La Vanguardia Readers’ Photos this photograph of this double rainbow in L’Escala, which lasted only three minutes, but was as fast as it was very spectacular due to its intensity.
A rainbow or rainbow is an optical and meteorological phenomenon that consists of the appearance in the sky of an arc (sometimes two or more) of multicolored light, caused by the decomposition of sunlight into the visible spectrum, which is It occurs by refraction, when the sun’s rays pass through small droplets of water contained in the Earth’s atmosphere.
It is an arch composed of concentric colored arcs, without a break between them, with red towards the outside and violet towards the inside.
Less common is the double rainbow, which we see in this case in L’Escala and which includes a second, fainter arc with the colors inverted, that is, red towards the inside and violet towards the outside.
Here, the rainbow covers, from the left, the popular Cargol rock, to the right inside the town of L’Escala. The Cargol rock is located where there was once a port known as Cargol and Punta de la Roca.
