MCQ
When light is incident on a doubly refracting crystal, two refracted rays-ordinary ray (O-ray) and extra ordinary ray (E-ray) are produced. Then
  • A
     Both O-ray and E-ray are polarised perpendicular to the plane of incidence
  • B
    Both O-ray and E-ray are polarised in the plane of incidence
  • C
    E-ray is polarised perpendicular to the plane of incidence and O-ray in the plane of incidence
  • ✓
     E-ray is polarised in the plane of incidence and O-ray perpendicular to the plane of incidence
✓

Answer

Correct option: D.
 E-ray is polarised in the plane of incidence and O-ray perpendicular to the plane of incidence
 E-ray is polarised in the plane of incidence and O-ray perpendicular to the plane of incidence
