Detailed Solution

Concept- When the light rays from the sun enters the atmosphere, the white light gets dispersed into its different colors that are violet, indigo, blue, green, yellow, orange and red by the drops of water in the atmosphere where the droplets act like prism and the sun’s light ray gets scattered through it.
