Why does a rainbow appear in the sky after a summer thunderstorm?

Rainbows are caused by reflection and refraction of sunlight hitting water droplets in the sky. After it rains, the air is rich in water vapor. When sunlight hits small water droplets, it will be refracted and dispersed into seven colors of light. Many small water droplets refract sunlight at the same time, and then reflect it into our eyes, and we will see a semicircular rainbow.
