STATEMENT-1: In amplitude modulation, the frequency of amplitude variation is much smaller than the frequency of modulated wave
STATEMENT-2 : Frequency of the signal is much smaller than the frequency of the carrier wave

In amplitude modulation, carrier wave frequencies are:

In amplitude modulation, carrier wave frequencies are:

The frequency of amplitude modulated wave is equal to

The frequency of amplitude modulated wave is equal to

A: The bandwidth of a modulated signal is 2f_(m) in amplitude modulation, where f_(m) is the frequency of the modulating signal. R: In case of amplitude modulation the frequency of a modulated signal is equal to the frequency of the carrier wave.

In an amplitude modulated wave for audio frequency of 500 Hz, the appropriate carrier frequency will be

Why is the amplitude of modulating signal kept less than the amplitude of carrier wave?
