A spectrum is a continuous range of entities, such as colors, frequencies, or values, often arranged by magnitude or wavelength, as seen when white light is split by a prism. In modern usage, it extends to abstract concepts like the political spectrum or the autism spectrum, highlighting the diversity and gradations within a category. This term underscores how phenomena can exist on a sliding scale rather than in absolutes, making it essential in fields from physics to social sciences.
