Explanation:
Detailed explanation-1: -The carrier frequency remains constant during AM.
Detailed explanation-2: -Frequency modulation is defined as changing the frequency of the carrier wave in accordance with the signals, but the amplitude remains same.
Detailed explanation-3: -The frequency range of AM waves is from 540 to 1600KHz. So the maximum frequency range is 1.6MHz which is less than 30MHz.
Detailed explanation-4: -In AM (Amplitude modulation) the frequency and the phase of the carrier signal remain constant.
Detailed explanation-5: -The frequency of the carrier wave is not altered in amplitude modulation.
