Because it's cheap and easy to generate radio waves, add information to them,
detect them at great distances, separate one from out of many, and recover the
information carried by the one you want. Plus, they cover the distance from one
place to another quite rapidly.
Radio waves are generated and modulated with the transmitted information at the transmitting station and radiated by its antenna. These radio waves are picked up by the receiver antenna, filtered from all the other transmitted signals, detected and demodulated by the receiver to recover the transmitted information.
Remote sensing
As time passes, the amplitude of AM radio waves is intentionally changed in order to add information to the waves that can be read at a distance.
remote sensing
Wireless G works by transmitting information through the air in various radio waves. Your computer can pick up the signals and use them to computer information.
Radio waves are utilized in one specific way by transmitting signals to carry information for communication, such as in radio broadcasting where radio stations use radio waves to broadcast music and news to listeners.

A Wi-Fi router modifies the waves it sends by encoding data onto radio waves and transmitting them through antennas. This process involves changing the frequency, amplitude, and phase of the waves to carry information.
Radio waves are generated and modulated with the transmitted information at the transmitting station and radiated by its antenna. These radio waves are picked up by the receiver antenna, filtered from all the other transmitted signals, detected and demodulated by the receiver to recover the transmitted information.
AM radio waves and radio waves in general are both electromagnetic waves used for transmitting information through the air. The main difference is that AM radio waves have a lower frequency and longer wavelength compared to other radio waves. This allows AM signals to travel longer distances but with lower audio quality compared to higher frequency radio waves.
Remote sensing
As time passes, the amplitude of AM radio waves is intentionally changed in order to add information to the waves that can be read at a distance.
The source is the RF current in the transmitting antenna.
RF stands for Radio Frequency, magnetic waves radiate out of the transmitting antenna and are picked up or recovered by the receiving antenna at the receiver.
