Is a rainbow a spectrum of colors?

Yes, a rainbow is a spectrum of colors that occurs when light is refracted, dispersed, and reflected in water droplets in the atmosphere. This phenomenon typically displays a sequence of colors: red, orange, yellow, green, blue, indigo, and violet. The arrangement of these colors is a result of different wavelengths of light bending at varying angles as they pass through the droplets. Thus, a rainbow visually represents the spectrum of visible light.
