spectrographic
Measuring wavelength patterns
Spectrographic describes something relating to or produced by a spectrograph—an instrument that separates light or other radiation into its component wavelengths for analysis.
Spectrographic analysis revealed the chemical composition of the distant star.
The term appears in astronomy, chemistry, and forensics wherever spectral data illuminates what something is made of.
