(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

Answer

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