In amplitude modulation, the sinusoidal carrier frequency used is denoted by $ \omega_{c} $ and the signal frequency is denoted by $ \omega_{m} $. The bandwidth $ \left(\Delta \omega_{m}\right) $ of the signal is such that $ \Delta \omega_{m} \ll \omega_{c} $. Which of the following frequencies is not contained in the modulated wave?

In amplitude modulation, the sinusoidal carrier frequency used is denoted by $ \omega_{c} $ and the signal frequency is denoted by $ \omega_{m} $. The bandwidth $ \left(\Delta \omega_{m}\right) $ of the signal is such that $ \Delta \omega_{m} \ll \omega_{c} $. Which of the following frequencies is not contained in the modulated wave?, $ \omega_{c}-\omega_{m} $, $ \omega_{m} $, $ \omega_{c} $, $ \omega_{m}+\omega_{c} $
