One of the mysteries of the English language finally explained.
(in double refraction) the light ray that does not obey the ordinary laws of refraction.Compare with ordinary ray
- ‘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.’
