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
rainbow sunlight is made up of seven colors. Violet, indigo bludgeon, yellow,
orange and red are the colures. When a toy of light is passed through a prism it
spits in to the so seven colors. Similarly, the falling drops of rain act like small prisms.
They split up the white sunlight in to its serene colors. We see them in the rainbow. It is a
bow 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 ceases, or the sun goes in, the
rainbow fades away.
