Spectroscopy in Action: How Light Reveals Secrets

Spectroscopy is the science of studying how light interacts with matter.
Every element absorbs and emits light at unique wavelengths—like a fingerprint.
Astronomers use spectroscopy to discover the composition of distant stars.
Doctors use it in MRI and blood analysis to detect molecules in the body.
Forensic scientists rely on spectroscopy to identify substances at crime scenes.
Infrared spectroscopy reveals bonds in molecules by how they vibrate with light.
Ultraviolet-visible (UV-Vis) spectroscopy tracks color changes to study chemical reactions.
Mass spectrometry, a cousin technique, sorts particles by their mass-to-charge ratio.
Raman spectroscopy is powerful for analyzing art, gems, and even pharmaceuticals.
From galaxies to fingerprints, spectroscopy turns invisible light patterns into knowledge.
