Vedclass · Accepted Answer

Because electromagnetic waves are plane-polarized,and the antenna must be parallel to the electric or magnetic field vector.

Vedclass · Answer

(B) Electromagnetic waves emitted by a broadcasting station are plane-polarized. This means the electric field vector of the wave oscillates in a specific plane. For maximum reception,the antenna of the portable radio must be oriented parallel to the direction of the electric field vector of the incoming electromagnetic wave. If the antenna is perpendicular to the electric field,the induced electromotive force $(EMF)$ will be minimal,resulting in poor or no signal reception.

Why is the orientation of the portable radio with respect to the broadcasting station important?
