An arcobaleno, or rainbow, is a meteorological phenomenon that occurs when sunlight is refracted, reflected, and dispersed in water droplets, creating a spectrum of light in the sky. Typically seen after rain, a rainbow appears as a multicolored arc, with red on the outer edge and violet on the inner edge. Rainbows are often associated with various cultural symbols and myths, representing hope and beauty. They can also be classified into primary and secondary rainbows, with the latter appearing outside the primary arc and displaying reversed color order due to additional reflections within the water droplets.
