Today we had some unusual weather. It started to rain in the evening but the sun was still bright in the sky.
The result:
This is the first time I have seen a double rainbow. Notice how the colors in the second rainbow is reversed! Science class ka kuch yaad aaya?!?
Update: Notice how the sky is brighter inside the rainbow. When I was taking the pictures, I did wonder but did not know the answer. But I know the answer now –
Reference – http://eo.ucar.edu/rainbows/
Why is the sky brighter inside a rainbow?
Notice the contrast between the sky inside the arc and outside it. When one studies the refraction of sunlight on a raindrop one finds that there are many rays emerging at angles smaller than the rainbow ray, but essentially no light from single internal reflections at angles greater than this ray. Thus there is a lot of light within the bow, and very little beyond it. Because this light is a mix of all the rainbow colors, it is white. In the case of the secondary rainbow, the rainbow ray is the smallest angle and there are many rays emerging at angles greater than this one. Therefore the two bows combine to define a dark region between them – called Alexander’s Dark Band, in honor of Alexander of Aphrodisias who discussed it some 1800 years ago!
