In amplitude modulation, sinusoidal carrier frequency used is denoted by \[{{\omega }_{c}}\]and the signal frequency is denoted by\[{{\omega }_{m}}.\]The bandwidth \[(\Delta {{\omega }_{m}})\] of the signal is such that\[\Delta {{\omega }_{m}}<<{{\omega }_{c}}.\]Which of the following frequencies is not contained in the modulated wave?    JEE Main Solved Paper-2017

A)  \[{{\omega }_{m}}+{{\omega }_{c}}\]                   

B) \[{{\omega }_{c}}-{{\omega }_{m}}\]

C)  \[{{\omega }_{m}}\]                                     

D)  \[{{\omega }_{c}}\]
