They are generated by the acceleration of charged particles, such as electrons, and are used for various communication and broadcasting purposes. Radio waves are characterized by their long wavelengths, which can range from several kilometers to a few millimeters.
The term "radio frequency" refers to the frequency of the wave, which is the number of cycles
Radio waves are used in a wide range of applications, including radio and television broadcasting, wireless
