Rainbows appear when sunlight is refracted, reflected, and dispersed by water droplets in the atmosphere. When light enters a raindrop, it bends and splits into its component colors, creating a spectrum. This light is then reflected off the inside surface of the droplet before escaping back into the air, forming a circular arc of colors that we see as a rainbow. Typically, rainbows occur after rain when the sun is shining, creating the right conditions for this optical phenomenon.
