Dispersion Forms a Spectrum
When white light is split into its constituent colours upon passing through a medium (like a prism), the phenomenon is known as dispersion. This process separates the light based on the wavelength of each colour.
The distinct band of seven colours (Violet, Indigo, Blue, Green, Yellow, Orange, Red - often remembered by the acronym VIBGYOR) obtained on a screen as a result of dispersion is specifically called a spectrum.
Therefore, the band of seven colours obtained on a screen due to dispersion is called a Spectrum.
