  "id": "MLC-T-CHM-003302",
  "term": "Dispersion",
  "field": "Chemistry",
  "definition": "The separation of electromagnetic radiation into its constituent wavelengths or frequencies. This phenomenon occurs when radiation passes through a medium where its refractive index varies with wavelength, causing different wavelengths to refract at different angles. A prism or diffraction grating can be used to achieve this separation, producing a spectrum.",
