Literary notes about spectrum (AI summary)
The word "spectrum" in literature assumes a dual role, both carrying scientific rigor and evoking rich, metaphorical imagery. In its scientific guise, it refers to the dispersion of light into its constituent hues—a process observed in phenomena like the solar and auroral spectra and explained through prisms and refractive indices [1, 2, 3, 4]. At the same time, literary authors harness "spectrum" to signify a broad continuum or range of qualities, emotions, or states, as seen when it describes human attributes or abstract concepts such as the varying intensities and hidden depths of character or experience [5, 6, 7]. By invoking this term, writers seamlessly bridge the objective observation of chromatic arrays with the subjective portrayal of life's multifaceted canvas [8, 9, 10].
