Explanation of Solution

Introduction:

The changing electric field around a charge creates a changing magnetic field. Similarly, the changing magnetic field around a charge creates a changing electric field. Due to continuous change in the electric and magnetic field, electromagnetic waves are produced.

The sound waves are converted into audio pulse and send to the antenna. The signal causes the electrons in the antenna to vibrate and produce electromagnetic waves. They produce electromagnetic waves that are transmitted into the air. The receiving antenna collects the electromagnetic waves and vibrates. The vibrating antenna sends a signal to the receiving device. The receiving device converts electromagnetic waves into an audio signal.

Conclusion:

Hence, all the steps through which radio stations use to broadcast sounds to a radio receiver.
