Detailed Solution

Red has the maximum wavelength.
She was splitting white light into its components. VIBGYOR is called dispersion. The maximum wavelength is red, and the minimum wavelength is violet. Red is the colour with the highest wavelength and the shortest frequency. Violet is the colour with the shortest wavelength and highest frequency.
When the entire spectrum of visible light passes through a prism, the wavelengths are separated into the colours of the rainbow because each colour is a different wavelength. For example, violet has the shortest wavelength at about 380 nanometres, and red has the longest wavelength at about 700 nanometres.
