extraordinary ray
Light passing through anisotropic crystals is doubly refracted with one or both ray directions not parallel to their wave normals. Such light rays do not follow Snell's law (n=(sin i)/(sin r)) of ordinary refraction and are termed "extraordinary." Also written Eray or e-ray. Compare: law of refraction
