Question

Quizplus · Accepted Answer

Rainbows are caused by the refraction, reflection, and dispersion of sunlight in water droplets in the atmosphere. The optical process that creates a rainbow is circularly symmetrical around the path of the sunlight, causing the rainbow to have a curved shape. The shape of the water droplets themselves also contributes to the arc shape of the rainbow.
