Modulation schemes depends on frequency.
FM stands for frequency modulation. The definition is: when the frequency of the carrier wave is changed in accordance with the intensity of the signal, it is called frequency modulation. In frequency modulation, only the frequency of the carrier wave is changed in accordance with the signal. However, the amplitude of the carrier wave remains unchanged.
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
AM - Amplitude Modulation FM - Frequency Modulation
Modulation Index is the ratio of the maximum deviation frequency to the frequency of modulation. In other words it is the ratio of the spread in frequency spectrum to the frequency that was used to modulate the carrier. For FM, modulation index is given by the formula mf= df/f where, mf=modulation index for FM df=difference in carrier frequency f=frequency of the signal
FM means frequency modulation AM means amplitude modulation
fc>2fm
frequency modulation..
a measure of the degree of frequency modulation expressed numerically for a pure tone modulation as the ratio of the frequency deviation to the frequency of the modulating signal.

" FM " is.
You can't do this unless you know more detail on the frequency modulator, like its modulation index, for example or the frequency deviation. For the amplitude modulator, it is easy. Bandwidth is twice the signal frequency so in this case the bandwidth is 178kHz for AM.
