(in double refraction) the light ray that does not obey the ordinary laws of refraction.
〔光学〕非常射线，非寻常光。比较ORDINARY RAY
Compare with ordinary ray
Example sentencesExamples
Thus, a straightforward new technique is demonstrated for determining the extraordinary-ray absorption coefficient.
The crystals are also idealized by assuming that no incident photon is absorbed, but each emerges in either the ordinary or the extraordinary ray.
He cited as an example Huygens's hypothesis that the extraordinary ray in doubly-refracting Iceland spar is propagated elliptically.
We present the behavior of the critical angle for the extraordinary ray as a function of the crystal axis position with respect to the normal to the refracting surface.
