Radio waves for Communication Radio waves are electromagnetic waves with wavelengths larger than the infrared light. Like all other electromagnetic waves‚ they travel at the speed of light. The wavelengths can vary from the size of a football field to the size of a football. They can be produced naturally by large stars and by lightning. Man-made radio waves are used for transmitting signals and currents. Specific Properties of Radio Frequency (RF) Current Radio frequency is the frequency of radio

FM Radio Reception? Background Information Communications are carried by waves. One type of communication is AM and FM radio. AM and FM radio’s use radio waves. A radio wave is an electromagnetic wave propagated by an antenna at various frequencies. In AM (amplitude modulated) radio waves‚ the audio signal changes the amplitude of the carrier wave. In FM (frequency modulated) radio waves‚ the audio signal changes the frequency of the carrier wave. Australia’s broadcast bandwidth for AM radio is 500-1500
