ignorant days! We did not realize the complicated
terms and theories involved. In the following
report you will see how we advanced in our
knowledge of radio waves, and we hope it will do
the same for you. Radio waves are a combination
of two kinds of electric vibrations. Audio
frequency waves, which represent voice and other
sounds and radio frequency waves, which carry
audio waves after being combined with them. Two
examples of broadcast waves are AM waves and
FM waves. AM which stands for amplitude
modulation, is a broadcasting method in which the
carrier waves (carry the sounds of a program) are
changed to match changes in the audio frequency

frequency modulation and these waves, that go
skyward, are......
