Ordinary wave

{
  "id": "MLC-T-CHM-008305",
  "term": "Ordinary wave",
  "field": "Chemistry",
  "definition": "One of two independent plane-polarized waves that propagate through an anisotropic medium, such as a birefringent crystal. This wave obeys Snell's law of refraction and has a refractive index that is independent of its direction of propagation. Its polarization is perpendicular to the principal plane of the crystal.",
