I know rainbows are from light hitting water droplets and being refracted essentially but I just don’t really understand how rainbows are the same every time. Why are they always the same shape and why are the colors always in that order?

I apologize if I sound dumb, I know this is some 5th grade stuff but it’s been awhile lol.
