Spectrometry Explained

In this interactive activity adapted from NASA, learn how scientists use the electromagnetic spectrum to identify materials. Animations illustrate how spectrometers separate light across the spectrum and how line spectra are created. Learn how patterns of absorption and emission lines can be used as fingerprints to identify the chemical composition of an object.

This media asset was adapted from Solar System Exploration: "Spectroscopy"/NASA.
