White light consists of a spectrum (range) of different frequencies and wavelengths - violet, indigo, blue, green, yellow, orange, red.
All these colours make up the spectrum of visible light.
A rainbow is seen when light falls on water droplets in the air and is refracted and dispersed into the different colours (violet, indigo, blue, green, yellow, orange, red) seen in the rainbow.
the light at the violet, indigo, blue range of the spectrum has the highest frequency (shortest wavelength) and orange and red light has the lowest frequency (longest wavelength).
