Detailed explanation-1: -When white light passes through a prism, a band of seven colours is obtained, which is called the spectrum. The seven colours in the spectrum are violet, indigo, blue, green, yellow, orange and red from down to up.
Detailed explanation-2: -Upon passage through the prism, the white light is separated into its component colors-red, orange, yellow, green, blue and violet. The separation of visible light into its different colors is known as dispersion.
Detailed explanation-3: -When a beam of white light is passed through a prism, it splits to form lights of seven colours.
