Spectral vs. Spectrum: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
"Spectral" relates to a spectrum or is characteristic of a spectrum, while "Spectrum" refers to a range of different things, often a band of colors or wavelengths.
Key Differences
"Spectral" is an adjective that describes something related to or resembling a spectrum. A spectrum is a range or band of something, especially colors visible in light or variations in wavelengths. Spectral thus often pertains to the analysis or representation of a spectrum, particularly in physics and optics, where it denotes the characteristic of different wavelengths of light or other electromagnetic radiation.

In the context of light, a spectral color is a color that is evoked by a single wavelength of light in the visible spectrum, as opposed to a mix of wavelengths. The term "spectrum," on the other hand, refers to the entire range of these wavelengths visible to the human eye, encompassing all possible colors from red to violet.

"Spectral" can also have broader, metaphorical uses, often relating to something ghostly or ethereal, as in "spectral presence." The word "spectrum," however, is more versatile and is used in a variety of contexts, from science (like the electromagnetic spectrum) to figurative uses, such as a spectrum of opinions or a spectrum in political ideologies.

In scientific applications, "spectral analysis" refers to the process of analyzing various properties of a spectrum, such as its intensity, wavelength, or frequency. "Spectrum," in a similar vein, can be used to describe a graphical representation of these properties, like a spectrum showing the intensity of light at different wavelengths.

Lastly, the term "spectral" is commonly used in conjunction with specific types of spectra, like "spectral lines" in atomic spectroscopy, which are specific wavelengths absorbed or emitted by an element. Conversely, a "spectrum" in this context would refer to the complete range of electromagnetic radiation absorbed or emitted by that element.
