  "term": "Dispersive medium",
  "field": "Meteorology and atmospheric science",
  "definition": "A medium in which the speed of wave propagation depends on the wave's frequency. Different frequency components of a wave travel at different velocities, leading to the spreading out or distortion of a wave packet over time. The Earth's atmosphere can act as a dispersive medium for certain electromagnetic waves.",
