spectrography
Wavelength recording technique
Spectrography is the technique of producing and analyzing spectra—the bands of light or other radiation separated by wavelength.
The term covers methods used to identify chemical compositions, study stellar atmospheres, or detect substances in forensic work.
A spectrograph is the instrument; spectrography is the practice of using it.
