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.
OMG. I think I get it now.
This is why we are in the centre because that’s the right angle to see it, and it being a circle is because again we are in the centre so it spans evenly. Is that correct?
Yes, exactly
You’re my second favourite Steve now, after Scuba Steve of course.
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, go crazy
Thanks. I am going to play with the hose. That sounds like a euphemism.
You’ve got the answer to the question, and I’m late to the party, but here’s a helpful graphic that also shows the inner and outer color band angles.
Thank you for breaking it down to this as well, I tried to get the comment above but this helped make a bing sound in my head
And thank you for asking in the first place
No problem. I have endless questions and sometimes they make it on here.
