Radio Frequency Waves
This chapter describes some of the scientific principles of radio waves that are fundamental to all types of broadcast transmission.
ELECTROMAGNETIC WAVES
It is fairly easy to understand that sound waves can be carried through the air, just as waves move on the sea. Sound waves are therefore a mechanical type of wave called longitudinal waves, which exist solely as disturbances within a medium. The medium can be of any state—solid, liquid or gas—but if no medium is present, this type of wave cannot exist (which is why there is no sound in a vacuum, for example). Light, on the other hand, is a so-called transverse wave, which exists independent of the medium through which it passes. ...
