Plane of polarisation is: This question has multiple correct options

1. the plane in which vibrations of the electric vector takes place
2. a plane perpendicular to the plane in which vibrations of the electric vector takes place
3. perpendicular to the plane of vibration
4. horizontal plane

Correct answer: a plane perpendicular to the plane in which vibrations of the electric vector takes place

Solution

In a polarized electromagnetic wave, the electric field vibrates in one fixed plane. The plane of polarization is taken as the plane perpendicular to that vibration plane, so the correct option is the one stating that relationship.
