My current event was about twelve kinds of rainbows. First people thought there were six, but now a French meteorologist called Jean Ricard (from the National Centre for Meteorological Research) says there are twelve. I thought there was only one kind. Scientists first thought rainbow colors came about mainly because of the angle you see the light at and the size of raindrops. But some rainbows might have more of certain colors because of different light wave lengths — based upon the distance of the sun from the horizon. Red has the longest wavelength and is seen more at sunrise or sunset. Blue and green have shorter wavelengths and are more visible when the sun is overhead.
I learned about something called the Alexander Band. It’s the dark area between two rainbows. The second rainbow is usually fainter and the colors are inverse to the first rainbow. Some rainbows don’t have Alexander bands; some do. Other kinds of rainbows have only red, orange, yellow, indigo or violet. That has to do mostly with where the sun is in the sky.
The rainbow with more red looks cool, I think. The only blue and red and also the only yellow, orange and red one looks pretty cool. I also like the classic rainbow (ROYGBIV).
I probably have seen other kinds of rainbows than the classic kinds. One day I went somewhere, and it kept raining on and off, and there were lots of rainbows that day. I bet there were a few of the non-classic kind, just I didn’t notice.
I got this news from Dogonews.com “Guess What? There are Twelve Kinds of Rainbows!” by Kim Bussing.
This is international news from Toulouse, France.
