  "term": "Planck function",
  "field": "Meteorology and atmospheric science",
  "definition": "A mathematical formula that specifies the spectral radiance of an ideal black body. It expresses this radiance as a function of both the body's absolute temperature and the frequency or wavelength of the emitted radiation. The function's peak shifts to shorter wavelengths as temperature increases, a principle described by Wien's displacement law.",
