Answer 4

actually they have no height, rainbows are actually circles

Answer 5

Physically, rainbows don't exist.

They are an optical illusion caused by light reflected off the INSIDE of raindrops. This reflection also causes a prism effect, so you see color bands.

But all of this takes place inside your eye.  You cannot touch a rainbow. It always seems to move away from you.

That's why it is said that there is a pot of gold at the end of the rainbow -- because you can never FIND the end of a rainbow.

Answer 6

It is nearby or far away, according to where the raindrops are, extending from the closest to the farthest illuminated drops along the elements of the rainbow cone
