  "id": "MLC-T-CHM-011167",
  "term": "Specular reflectance",
  "field": "Chemistry",
  "definition": "The ratio of the radiant power reflected from a surface in a mirror-like fashion to the total radiant power incident on that surface. This type of reflection occurs when light strikes a smooth interface and is reflected at an angle equal to the angle of incidence. It is a dimensionless quantity, often expressed as a percentage.",
