A rainbow is full of colors and it makes the sky more beautiful. I have a lot of doubts about Rainbows, but I didn't express to anyone. I think this is the right place to ask. Following are some doubts I have about rainbows.
What causes the rainbow?
Why is the rainbow colored?
Why is the rainbow round?
Is it actually possible to see two rainbows at the same time?
