  "term": "Spectrometer",
  "field": "Chemistry",
  "definition": "An instrument that measures the intensity of electromagnetic radiation as a function of its wavelength or frequency. It consists of an entrance slit, a dispersion element like a prism or grating, and an exit slit or detector. Spectrometers are used to analyze the spectral composition of light emitted, absorbed, or scattered by a sample.",
