Spectrum is the intensity of light as it varies with wavelength or frequency.
A spectrum is a state that can fluctuate without gaps across a continuum and is not constrained to a particular range of values (plural: spectra or spectrums). After passing through a prism, visible light takes on a rainbow of hues, which is how the term was initially used scientifically in optics.
Angles at which light is refracted vary depending on its color. A colorful spectrum is produced by the difference in the refraction angles of the various colors during refraction.
The distribution of the amplitudes and phases of each frequency component against frequency is known as the frequency spectrum of an electrical signal.
