WebApr 27, 2024 · Radio waves travel at the same speed as light because they are like light waves, except that they are unseen. Radio waves can equally travel through various mediums at different speeds. How fast they are going to travel through a specific medium will be determined by some factors. Frequency modulation or FM is a form of modulation which conveys information by varying the frequency of a carrier wave; the older amplitude modulation or AM varies the amplitude of the carrier, with its frequency remaining constant. With FM, frequency deviation from the assigned carrier frequency at any instant is directly proportional to the amplitude of the (audio) input signal, determining th…

WebVery high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter.
