Selecting a reception range

Radio waves Ñ medium wave, long
wave and short wave Ñ offer a wide
range of reception, because the broad-
cast signals travel not only along the
ground as surface waves, but also as
waves bounced back to earth from the
ionosphere.
Frequency Modulation (FM) provides
substantially better sound quality than
Amplitude Modulation (AM). However,
because FM transmissions rely on line-
of-sight broadcast waves, their effec-
tive reception range is limited.
