The perfect explanation of radio to children or adults!
Millions of radio waves--carrying sound wave signals and digital signals--reach your receiver every second. The receiver's tuner picks out a specific signal. Its amplifier strengthens that signal. A demodulator separates the signal from the carrier wave. And then a speaker converts the signal to the sound waves that you hear!
Radio is a way of sending sounds or other information through the air. The information is carried by invisible radio waves. Radio waves are used for broadcasting, or sending out, radio and television programs. Radar, cell phones, cordless telephones, wireless computer networks, and other forms of communication use radio waves, too.
No particles of water, air, or any other substance can carry radio signals. A radio wave is a special combination of electric and magnetic forces. These forces can be seen at work with commonplace objects. A magnet spreads energy through space to pick up iron filings, tacks, and other light bits of iron.
