As I said in the other one, rainbows are not reflections. Instead, they are a phenomena that arises out of the principles of the refraction and convergence of light through the rain droplets that remain in the sky after a storm, not unlike how a prism separates sunlight into the colors of the rainbow. Seeing as reflection has nothing to do with rainbows, I propose that people with low intelligence should get their facts straight before insulting those with apparently lower brain powers.
The difference between ignorant and stupid is that an ignorant person can learn while a stupid person clings to their beliefs even while faced with proof to the contrary. Now that I have shown you that reflection does indeed occur during the formation of a rainbow, do you concur that a rainbow is a reflection of the sun?
