What is a rainbow ?

A rainbow is seen when it is raining and sunny at the same time.
When it rains , the rays of the sun hit the raindrops , splitting then into seven colors and bending them as it passes through to form an arch of colored light. From the outside (or east ), the colors are –Red , Orange , Yellow, Green, Blue , Indigo and Violet.
As for the gold at the end of the rainbow, nobody’s found it yet !
