For wireless communication of data there are uses of modulation.
AM (Amplitude Modulation): means altering the length of amplitude (crest and trough)
FM (Frequency Modulation): means altering the length of frequency (i.e. varying the wavelength)
FM is considerably preferable to that with AM because of its long range, low power consumption, and versatile tuning.

has no information. The radio station adds information to it by varying its amplitude.

The commercial AM band in the US is channelized in 10 KHz increments. If you find a station with their carrier centered at 825 KHz, then the station has a serious problem. They could be licensed at 820 or 830 ... or another multiple of 10 ... but not at 825.

Which has a higher frequencies am radio waves or fm radio waves?
FM radio has the higher frequency which is why it sounds better. AM is a lower frequency but can travel further because the waves bounce off
What is the frequency of radio wave?
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
What is a radio wave's relative wavelength and frequency compared to other waves in the Electro-Magnetic Spectrum?
Radio waves are the lowest frequency (and therefore longest wavelength) waves in the electromagnetic spectrum.
What has a greater frequency am waves or FM waves?
FM waves are of higher frequency than am waves.AM radio ranges from 535 to 1705 kilohertzFM radio ranges in a higher spectrum from 88 to 108 megahertz.
What frequency does radio waves use?
Radio frequency (RF) is a rate of oscillation in the range of about 30 kHz to 300 GHz
What electromagnetic wave have the lowest frequency?
Radio Waves.
How are radio and television waves added to em radio waves?
by changing the amplitude or frequency of the radio waves.
What radio waves?
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
What is the frequency range of radio waves that can penetrate human body?
The frequency range that the radio waves can penetrate the human body is between 1Hz and 10 KHz. This frequency of the radio waves is however not dangerous.
How are radio waves and television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
How are radio and television waves added to em waves?

What do radio waves have the lowest of?
frequency
How are radio television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
What is a low frequency wave?
Radio waves are the lowest frequency waves. Next are microwaves, then infra-red waves.
What wave has the lowest frequency of electromagnetic waves?
Radio waves
Which type of waves have a frequency of 100000 Hz?
Ultrasound or quite-low-frequency radio waves have.
