Question

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 produced. Then, (B) both O-ray and E-ray are polarised in the planed of incidence (C) E-ray is polarised in the plane of incidence and O-ray perpendicular to the plane of incidence (D) E-ray is polarised perpendicular to the plane of incidence and O-ray in the plane of incidence.

Correct answer is (c) E-ray is polarised in the plane of incidence and O-ray perpendicular to the plane of incidence

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,

both O-ray and (E-ray) are produced. Then,

both O-ray and E-ray are polarised in the planed of incidence

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

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

Correct answer is (c) E-ray is polarised in the plane of incidence and O-ray perpendicular to the plane of incidence
