When sunlight is dispersed and reflected by water droplets?

When sunlight passes through water droplets, it is both refracted and reflected, resulting in the dispersion of light into its component colors. This phenomenon creates a spectrum that forms a rainbow, as the different wavelengths of light bend at slightly different angles. The light is first refracted as it enters the droplet, reflected off the back surface, and then refracted again as it exits, resulting in the vivid arc of colors typically seen in a rainbow. This process is most commonly observed when sunlight shines after a rain shower.
