  "term": "Radiation constants",
  "field": "Chemistry",
  "definition": "Physical constants that appear in equations describing the properties of electromagnetic radiation, particularly black-body radiation. These include the first and second radiation constants, which are derived from fundamental constants like the Planck constant and Boltzmann constant. The first radiation constant is 2πhc^2, and the second is hc/k.",
