Answer:
The prism splits the incident light beam into a band of 7 colors. This band of colored components of a light beam is called its spectrum and the phenomenon of splitting of light into its component colours is called dispersion.

The statement is true. The band of the coloured components of a light beam is called VIBGYOR.
Explanation:
- Light has an electromagnetic spectrum that extends from ultraviolet radiation to infrared radiation.
- Ultraviolet radiation has the highest frequency and lowest wavelength whereas infrared rays have highest wavelengths and lowest frequencies.
- Coloured visible range of wavelength in light spectrum extends from 380 nanometers to 780 nanometers.
- Lowest wavelength of 380 nm corresponds to violet colour and 780 nm i.e. highest in visible range corresponds to red colour.
- Violet -Indigo - Blue - Green - Yellow - Orange - Red
- These coloured components in white light is visible as a result of refraction or dispersion.
