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.
The carrier wave is the elecronic signal they broadcast. The carrier wave on its own
has no information. The radio station adds information to it by varying its amplitude.
Wavelength = [ speed of light (and radio) ] divided by (frequency) Wavelength = (299,792,458 meters / sec) / (825,000 Hz) = 363.38 meters (rounded) By the way ... 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.
No higher than 1090kHz and no lower than 1110 kHz.
Any frequency lower than 89.9 MHz and higher than 90.1 MHz
Wavelength = (speed) / (frequency) = (3 x 108)/(1.13 x 106) = 265.3 meters (rounded)

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
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
Radio waves are the lowest frequency (and therefore longest wavelength) waves in the electromagnetic spectrum.
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.
Radio frequency (RF) is a rate of oscillation in the range of about 30 kHz to 300 GHz
Radio Waves.
by changing the amplitude or frequency of the radio waves.
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
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.
