Everyone knows two things about rainbows: they have rounded shape and they are colorful. June 5 a resident of the village of Dover in Pennsylvania (USA) saw a rainbow that does not fit this description. According to her, it was strange — rainbow was red and practically horizontal.
Nevertheless, it's a rainbow!
Why is it only red? Because there is only red color. All the other colors of the rainbow were scattered by air molecules and dust particles before low-hanging sun. Sunset rainbows are often red, since the intensity of scattering and refraction for different wavelengths are not the same. At sunset the rays of the sun go a long way in the atmosphere and long-wave light (blue) scatters less than short-wave. As a rule, red rainbows still form a complete arc, but this did not work — from behind the clouds. The shadows of clouds near the setting sun stretched across the sky, dimming the greater part of the rainbow. There is only one almost horizontal band.
