In a rainbow, purple (A) is dispersed more. This is due to the phenomenon of dispersion, where different wavelengths of light refract at slightly different angles when passing through water droplets. Purple light, having a shorter wavelength, bends more than other colors such as red (which has a longer wavelength). As a result, purple light is spread out more than the other colors, causing it to appear on the inner edge of the rainbow. The degree of bending, or refraction, increases with decreasing wavelength, which is why purple, being at the shorter end of the visible spectrum, is dispersed the most. This dispersion results in the separation of light into its constituent colors, creating the spectrum of a rainbow with purple on the inner edge and red on the outer edge.
