" In frequency modulated wave "

What are the main difference between amplitude modulated and frequency modulated waves?

A frequency modulated wave is formed by superimposing a data signal of frequency 500 Hz on a carrier wave of amplitude 15 V and frequency 40 MHz, with modulation index of 0.01. Establish the equation of the FM wave.

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

A modulating wave of frequency 100 MHz and amplitude 100V is superimposed on a carrier wave of frequency 300 GHz and amplitude 400V . The value of modulating index and difference between the maximum frequency and minimum frequency of modulated wave are respectively :

The amplitude modulated (AM) radio wave bends apreciably round the cornes of a 1mxx1m board but the frequency modulated (FM) wave only negligible bends.If the average wavelengths of AMandFM waves are lamda_0 and lamda_f .

It is observed that amplitude modulated (AM) radio wave shows appreciable diffraction when it encounters an opening of size 75 cm xx 75 cm. In such a case, diffraction shown by frequency modulated (FM) wave is very negligible. If lambda_A and lambda_F represent average wavelengths of AM and FM waves, then
