What property of a radio wave defines its polarization?

  1. The orientation of the electric fieldپاسخ درست
  2. The orientation of the magnetic field
  3. The ratio of the energy in the magnetic field to the energy in the electric field
  4. The ratio of the velocity to the wavelength

توضیح

Polarization is defined by the plane in which the electric field lies, so a wave with a vertical electric field is vertically polarized. The magnetic field is always perpendicular to it and is not used for the definition.
