spectrometer

A spectrometer is a scientific instrument used to analyze light by splitting it into its individual colors or wavelengths. This process reveals information about the composition or properties of the object emitting or reflecting the light. For example, spectrometers can identify the elements in a star, determine the purity of a substance, or analyze a chemical sample. They work by measuring the intensity of different wavelengths, creating a spectrum that acts like a fingerprint for various materials. Overall, spectrometers are essential tools for understanding the chemical and physical characteristics of objects through their light.
