The good things make you wait. It has taken us a while to be able to enjoy a hopeful landscape like the one offered by Blanes beach, in the La Selva region, in this snapshot that I have captured for La Vanguardia’s Readers’ Photos.
We have finally had a few hours of rain, although, in this context of drought, perhaps the rainbow has rushed to announce the return of good weather.
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. .
