  "term": "Reflectance",
  "field": "Chemistry",
  "definition": "The ratio of the radiant flux reflected by a surface to the radiant flux incident upon it. This quantity describes the ability of a material to reflect electromagnetic radiation. It is a dimensionless value, often expressed as a percentage, and varies with wavelength and angle of incidence.",
