spectra

Prism's color outputs

Spectra is the plural of spectrum, most often encountered in scientific contexts.

A spectrum is the distribution of something across a range, originally and most famously visible light spread into its component colors by a prism.

Scientists analyze spectra to identify chemical compositions, measure temperatures, or detect motion in distant objects.

The word appears in physics, astronomy, and chemistry wherever wavelengths or frequencies are being examined: The spectra of these stars indicate they contain heavy metals.
