FM radio

Madison Goldstein and Gabbi Fernandez

In 1933, FM radio was patented by inventor, Edwin H. Armstrong

FM stands for frequency modulation

After World War ll, the FM radio broadcast was introduced in Germany

Because the transmitter at the radio station has converted the sound waves into electromagnetic waves, which are then encoded onto an electromagnetic wave in the radio frequency range (generally in the range of 500-1600 kHz for AM stations, or 86-107 MHz for FM stations). Radio electromagnetic waves are used because they can travel very large distances through the atmosphere without being greatly attenuated due to scattering or absorption


Fun Fact:
FM radio stations all end in an odd number
