Question

Define O-ray and E-ray.

Answer 1

This process, first reported by Erasmus Bartholinus in 1669, is called double refraction. The two rays of light are each plane polarized by the calcite such that the planes of polarization are mutually perpendicular. ... The other ray (and anyray that does not obey Snell's Law) is an extraordinary ray (or E-ray).

Answer 2

Answer:

The O-ray stands for Ordinary ray and E-ray stands for Extraordinary ray. Introduction: Double refraction or Birefringence is special optical property which is observed in distinct type of anisotropic crystals such as calcite, quartz, KDP, rutile etc. Both O-ray and E-ray are associated with this
