Now I know that rainbows are formed due to refraction of light from the sun hitting raindrops and light waves leave at varying angles between 40-42 degrees or somewhere around there. Also, that they’re round.
What I don’t understand is how it’s consistent, like I assume it’s hitting many raindrops, but all these drops are in different places so why does it still form a nice circle. Furthermore, why isn’t the whole sky a rainbow if it’s raining and thus hitting all the drops. I suspect the angle of the sun is playing a part but I’m not a science man.
Please help me get this thought out of my head.
Yes. And it’s rare on cloudy days because the rainbow only works if you have a point-source of light. Clouds diffuse the light so instead you get an infinite amount of rainbows, all overlapping back into white.
I recommend you find a garden hose nozzle with a mist option. See the circle rainbow, taste the circle rainbow, hunt the double rainbow, find the rearward rainbow. go crazy.
Thanks. I am going to play with the hose. That sounds like a euphemism.
