I know that the equation of armonic motion depends on three parameters: amplitude, frequency, phase. When a radio is receiving a signal from another radio, they’re on the same wavelength, that’s measured by period/frequency; so I guess that’s a “fixed” variable, or at least a variable that doesn’t carry information, but permits to choose which signal to listen to.
So how does a wave transfer information? Is it because the other two parameters change (or at least its amplitude).

For AM, it’s a series of Amplitude Modulation changes. For FM, it’s a series of Frequency Modulation changes, hence the naming conventions
