Amplitude modulation transmits sound waves by adjusting the amplitude of the radio wave, or carrier wave. With AM transmissions, the frequency is kept constant and the amplitude of the carrier wave is changed.
Frequency modulation transmits sound by adjusting the frequency of the radio wave. With FM the amplitude of the radio wave stays constant, while the frequency fluctuates around a basic carrier wave.

AM stand for Amplitude Modulation and FM stands for Frequency modulation. Both of these techniques are used to transmt data. For more details, read it on wikipedia.

AM is amplitude modulation, while FM is Frequency modulation.
The difference is that (put very simply) AM varies the amplitude to send signal but FM modulates (varies) the frequency it is sent on.

AM- Amplutude Modulation
FM-Frequency Modulation
The differance is that The FM stations are close together and the AM stations are far apart.
