What determines the frequency of radio waves?

The frequency of radio waves is determined by the oscillating changes of electric and magnetic fields. Radio waves are a type of electromagnetic radiation, and they are produced when charged particles undergo acceleration, causing oscillations in electric and magnetic fields. These fields propagate through space and generate radio waves.

The frequency of these waves is essentially the rate at which the oscillations occur; it is how quickly the electric and magnetic field components change direction and magnitude. This oscillation is independent of external factors such as temperature or light intensity, as radio waves are a product of electromagnetic field behavior rather than sound or visible light properties. Thus, the correct understanding of radio wave frequency centers on the dynamics of these electric and magnetic fields, which give rise to the radio waves we utilize for various communication technologies.
