What is AM radio vs FM radio ??!
Question: AM Radio is Amplitude Modulation and FM is Frequency Modulation.
The AM radio band is different in various parts of the world, but here in North America the AM band for public radio is 520 kHz–1,610 kHz. AM works by varying the strength of the transmitted signal in relation to the information being sent. For example, changes in the signal strength can be used to reflect the sounds to be reproduced by a speaker.
The FM radio band is consistent the world over working in the 87.5 to 108.0 MHz spectrum. In Europe the stations work on even decimals (eg 99.2, 99.4) and in North America uneven (eg 99.3, 99.5). FM conveys information over a carrier wave by varying its frequency. In analog applications, the instantaneous frequency of the carrier is directly proportional to the instantaneous value of the input signal.

AM is talk while FM is music
Basically where the frequencies are in the radio wave spectrum and how it's broadcast
