Rainbow is caused by the reflection, dispersion, and refraction of light in water droplets resulting in a spectrum of light that appears in the sky. Rainbow is caused by sunlight appears in the section of sky opposite to the sun. It is made up of seven colors i.e. red, yellow, orange, green, indigo, blue, and violet.
