  1. TELECOM V = f x l m/s hz m V is speed ,f is frequency l is wavelength

  2. TELECOM • v =d/t • v is speed in m/s • d is distance in m • t is time ins

  3. TELECOM • Radio waves are carried from transmitter by the carrier wave. • Speed of radio waves is • 300,000,000m/s

  4. TELECOM • The main parts of a radio receiver are • Aerial – receives all signals • Tuner – tunes into one particular signal

  5. TELECOM • Decoder – separates the carrier wave from the audio (sound ) wave • Amplifier gives a bigger copy of the audio wave

  6. TELECOM • LOUDSPEAKER TURNS THE ELECTRICAL SIGNAL INTO SOUND • DIFFERENT RADIO STATIONS ARE IDENTIFIED BY THE CARRIER WAVE FREQUENCY

  7. SPACE • Radio waves are detected by large curved dishes similar to the dish aerials in T.V. systems
