Chapter 26.2, Problem 26SSC

To determine

The direction of the electric fields in radio signals.

Explanation of Solution

Introduction:

An antenna can be defined as an interface between spatially propagating radio waves and electrical currents that is passing throughmetal conductors that are used by transmitters or receivers.

Theconductorsof antenna are responsible for generating electric fields. Due to potential difference across the end of the antenna, electric field is produced. From this fact, we can conclude that direction of electric field is parallel to the conductor's direction. In this given case, since the conductor is placed horizontally, the electrical fields in the television signals will also be in horizontal direction since both have same direction.

Conclusion:

Hence,the electric fields in television signals will also be in horizontal direction.
