Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
(in double refraction) the light ray that does not obey the ordinary laws of refraction.Compare with ordinary ray
- ‘The crystals are also idealized by assuming that no incident photon is absorbed, but each emerges in either the ordinary or the extraordinary ray.’
- ‘Thus, a straightforward new technique is demonstrated for determining the extraordinary-ray absorption coefficient.’
- ‘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.’
We take a look at several popular, though confusing, punctuation marks.
