A rainbow is a beautiful sight. It is an arch of colored light in the sky. To see this rain and sunshine should occur at the same time. What makes a rainbow? Sunlight is made up of seven colours.violet, indigo, blue, green, yellow, orange and red are the colours.when a ray of light is passed through a prism it spasm it splits into these seven coloures.similarly, the falling drops of rain act like small prisms. They split up the white sunlight into its seven coloures.we see them in the rainbow. It is a bow or an arch, made by the rain. That is the main reason that there must be rain and sunshine at the same time for the formation of a rainbow. When rain ceasea or the sun goes in, the rainbow fades away.
