Answer:
A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. When light exits the droplet, it makes a rainbow.

Explanation:
1)Every rainbow that shines in the sky consists of seven colors. Furthermore, these colors are Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Commonly people call them VIBGYOR that is a short form of these colors.
2)Rainbows are formed due to the combined effect of three phenomena, namely, reflection, refraction, and dispersion of light.
