Radio waves are produced by the accelerated motion of charges in conducting wires. They are used in radio and television communication systems. They are generally in the frequency range from 500KHz to about 1710KHz . Higher frequencies up to 54MHz are used for short wave bands .
TV waves range from 54MHz to 890MHz . The FM(frequency modulated)radio
band extends from 88MHz to 108MHz . Cellular phones use radio waves to transmit voice communication in the ultrahigh frequency (UHF) band .
