A message signal of frequency \( \omega_{m} \) is superposed on a carrier wave of frequency \( \omega_{C} \) to get an amplitude modulated wave (AM). The frequency of the \( \mathrm{AM} \) wave will be
(a) \( \omega_{m} \)
(b) \( \omega_{C} \)
(c) \( \frac{\omega_{C}-\omega_{m}}{2} \)
(d) \( \frac{\omega_{C}+\omega_{m}}{2} \)
