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 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
