Spectroscopy
Spectroscopy is a scientific technique used to examine the properties of light within a specific portion of the electromagnetic spectrum to identify matter. It works on the principle that each element absorbs or emits light at distinct wavelengths, creating a kind of 'fingerprint'. By observing these fingerprints, scientists can determine the composition of various substances, from stars to chemical compounds. It's akin to decoding messages contained in light to reveal secrets about the universe or unknown substances.

Spectroscopy is a scientific technique used to analyze the light emitted, absorbed, or scattered by materials. When substances interact with light, they produce specific patterns, or spectra, that act like unique fingerprints. By studying these patterns, scientists can identify the composition, structure, and properties of the material. This method is widely used in fields like chemistry, astronomy, and biology to learn about everything from distant stars to the makeup of drugs. Essentially, spectroscopy helps us understand the world around us by examining how light interacts with matter.
