In the Photos of the Readers of La Vanguardia we can see the splendid rainbow that was seen this afternoon in Campdevànol, in the region of Ripollès.
A rainbow is an optical and meteorological phenomenon that consists of the appearance in the sky of one arc (or, in this case, two) of multicolored light.
It is caused by the decomposition of sunlight into the visible spectrum, which occurs by refraction, when the sun’s rays pass through small droplets of water contained in the Earth’s atmosphere.
Although the rainbow is a continuous gradient of spectral colors, it is considered that these can be defined in seven fundamental colors: red, orange, yellow, green, cyan, blue and violet, which are equivalent to those mentioned by the scientist Isaac Newton in 1704. .
Less common is the double rainbow, which includes a second, fainter arc with the colors inverted, that is, red towards the inside and violet towards the outside.
In this case we can see parts of the rainbow in detail with the bell tower of the parish church in the foreground. This temple dates back to the 18th century, although it was rebuilt in 1945 due to the aftermath of the civil war and the earthquake of 1944. The fantastic 46-meter-high bell tower stands out.
