  "id": "MLC-T-MET-009137",
  "term": "Spherical wave",
  "field": "Meteorology and atmospheric science",
  "definition": "A wave whose wavefronts are concentric spheres expanding or contracting from a central point source. The amplitude of a spherical wave decreases with distance from the source, typically inversely proportional to the distance in an ideal medium. This wave type is observed in sound propagation from a point source or in electromagnetic radiation emanating uniformly in all directions.",
