Question

Quizplus · Accepted Answer

Rainbows are formed due to the refraction and reflection of sunlight through water droplets in the atmosphere. The droplets act as small prisms that refract the incoming sunlight and separate it into its different colors. This optical process is circularly symmetrical around the path of the sunlight, resulting in the curved shape of the rainbow.
