Electromagnetic waves are radiated by electric charges when they are accelerated. Radio waves, electromagnetic waves of radio frequency, are generated by time-varying electric currents, consisting of electrons flowing through a metal conductor called an antenna which are changing their velocity and thus accelerating. An alternating current flowing back and forth in an antenna will create an oscillating magnetic field around the conductor. The alternating voltage will also charg… WebThe process of combining an audio wave with a carrier wave is called modulation. Sound waves are converted by microphones into electrical waves, amplified, and then combined with the CW radio wave. Figure 13. …
