Diffuse reflectance

{
  "id": "MLC-T-CHM-003185",
  "term": "Diffuse reflectance",
  "field": "Chemistry",
  "definition": "The reflection of electromagnetic radiation from a rough surface such that the reflected rays are scattered in many directions, rather than being reflected at a single angle. This phenomenon occurs when light penetrates the surface and interacts with the bulk material before being re-emitted. It is often used in spectroscopy for analyzing opaque or powdered samples.",
