modulation
In FM, which is frequency modulaton, the information is "put onto" the radio waves by varying the frequency of the wave. In AM, which is amplitude modulation, the information is "put onto" the radio waves by varying the amplitude of the wave.
A radio station uses a process called modulation to imprint information onto radio waves. This involves varying the properties of the radio wave, such as its amplitude, frequency, or phase, to encode the desired audio signal. The receiver then demodulates these modified waves to extract the original information.

Electromagnetic energy
Radio waves are electromagnetic waves that carry energy. When these waves are absorbed by the radio's antenna, they induce electrical currents in the circuitry of the radio. This process allows the radio to convert the energy from the radio waves into sound, enabling us to hear broadcasts. However, radio waves themselves do not heat; it is the conversion of that energy into electrical signals that allows the radio to function.
The electromagnetic spectrum includes visible light radio waves and infrared ultraviolet and x-rays.
The process by which information is carried by electromagnetic waves is called modulation. This involves varying the characteristics of the electromagnetic waves, such as amplitude, frequency, or phase, to encode the information being transmitted.
Yes, radio waves consist of photons, which are particles of light. In the electromagnetic spectrum, radio waves interact with each other by varying in frequency and wavelength, allowing them to carry information over long distances through modulation and demodulation processes.
FM waves, or frequency modulation waves, are a type of electromagnetic wave used in radio broadcasting. They carry audio information by varying the frequency of the wave, resulting in clearer sound quality and less susceptibility to interference compared to AM waves. FM radio stations are assigned specific frequencies to prevent signal overlap.
no, mechanical waves are not radio waves
Radio waves ARE electromagnetic waves.
Transverse. Radio waves are electromagnetic waves, which are transverse.
