101. Sound is sent from the radio station through the air to your radio by means of electromagnetic waves. News, music, Bible teaching, baseball games, plays, advertisements- these sounds are all converted into electromagnetic waves (radio waves) before they reach your radio and your ears. 102. At the radio station, the announcer speaks into a microphone. The microphone changes the sound of his voice into an electrical signal. This signal is weak and can't travel very far, so it's sent to a transmitter. The transmitter mixes the signal with some strong radio signals called carrier waves. These waves are then sent out through a special antenna at the speed of light! They reach the antenna of your radio. Your antenna "catches" the signal, and the radio's amplifier strengthens the signal and sends it to the speakers. The speakers vibrate, and your ears pick up the vibrations and your brain translates them into the voice of the radio announcer back at the station. When you consider all the places the announcer's voice travels 103. Every radio station has its own frequency.
