At the End of the Rainbow

Unfortunately your answer is incorrect.

The strength of the rain does not influence the size of the rainbow. On the contrary, a stronger rainfall can lead to observing the colours more intensely. To solve the task, you will have to consider under which conditions a rainbow forms and find out why it is arched. Can a rainbow make up a whole circle?

You have not found the right answer yet, but looking at another hint can show you the right way. Do not feel discouraged, use another hint and think about it again.
