Water droplets act like tiny prisms in the atmosphere, dispersing and refracting sunlight. When sunlight enters a water droplet, it is separated into its constituent colors due to dispersion, and then the different colors are refracted as they exit the droplet. This process happens millions of times within countless water droplets, resulting in the formation of a rainbow when the dispersed and refracted light reaches our eyes.
