Rainbows are one of the most beautiful natural phenomenon seen on Earth. A rainbow can be seen when the sun appears in the sky after a heavy rainfall. Sunlight consists of seven colours — violet, indigo, blue, green, yellow, orange and red, or VIBGYOR — that combine to make white light. When sunlight enters raindrops in the air, the different colours get separated to form the rainbow.
