Sentences with word «spectroscopic»
"Spectroscopic" refers to the study or analysis of light emitted or absorbed by substances. It involves using special tools and techniques to examine the different colors and wavelengths present in the light, helping scientists understand the chemical composition and properties of the substances being observed. Full definition
