Spectral vs. Spectrum — What's the Difference?
By Fiza Rafique & Urooj Arif — Updated on March 11, 2024
Spectral refers to anything pertaining to a spectrum or specters, often implying ghostly or immaterial qualities. Spectrum, however, denotes a range of different things, usually colors or wavelengths, observed under specific conditions.

Key Differences
Spectral often suggests an association with ghosts or the supernatural, characterized by its ghostly or ethereal nature, whereas spectrum typically refers to a band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength.
Spectral characteristics or phenomena usually relate to the specific properties of light as it pertains to a spectrum, such as spectral lines in physics, whereas the term spectrum can refer to a wide range of fields including light, sound, and other continua of measurable quantities.
Spectral analysis deals with the decomposition of physical signals into their spectral components, often used in various scientific fields to analyze the properties of waves or materials. Spectrum, on the other hand, is the result of such analyses, representing the distribution of signal energies as a function of frequency or another variable.
In literature and art, spectral is used metaphorically to describe eerie, ghost-like aspects of characters, settings, or themes, conveying a sense of mystery or otherworldliness. In contrast, spectrum can be used metaphorically to describe a wide range of different things or ideas within a particular concept or category, emphasizing diversity or comprehensiveness.
While spectral emphasizes qualities or characteristics that are ghostly or pertaining to a narrow aspect of light or waves, spectrum encompasses a broader range of meanings, often used to denote a comprehensive array or a continuous sequence of values spanning between two extremes.
