Q. 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 polarized perpendicular to the plane of incidence
B) Both $O$-ray and $E$-ray are polarized in the plane of incidence
C) $E$-ray is polarised perpendicular to the plane of incidence and $O$-ray in the plane of incidence
D) $E$-ray is polarized in the plane of incidence and $O$-ray perpendicular to the plane of incidence
Explanation
The correct answer is Option D: $E$-ray is polarized in the plane of incidence and $O$-ray perpendicular to the plane of incidence.
A detailed explanation for this question is being prepared.
