Questions  

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
d
E-ray is polarised in the plane of incidence and O-ray perpendicular to the plane of incidence

detailed solution

Correct option is D

E - ray  consists vibrations parallel to plane of incidence.
