spectra
[ หspษktrษ ]
science, physics
Spectra are the plural form of spectrum, representing the range of different colors or frequencies of light or other waves. They can also refer to various distributions of qualities or characteristics among a set, often used in physics and chemistry to describe the distinct lines or bands of colors produced when light is dispersed.

Etymology
The word 'spectrum' originates from the Latin word 'spectrum', meaning 'image' or 'apparition'. It was first used in English in the early 17th century to describe the spectrum of light visible when a beam passes through a prism. The term was then used in a broader sense in the 19th century to encompass various ranges of things, such as the electromagnetic spectrum, which includes all wavelengths of light, and in scientific contexts to depict distributions of phenomena. The form 'spectra' is simply the plural of 'spectrum', further extending its application in fields like physics, chemistry, and psychology to describe collections of data or observations that reflect a range of qualities or characteristics.
