    A block M hangs vertically at the bottom end of a uniform rope of constant mass per unit length. The top end of the rope is attached to a fixed rigid support at O. A transverse wave pulse (Pulse 1) of wavelength lamda_(0) is produced at point O on the rope. The pulse takes time T_(OA) to reach point A. If the wave pulse of wavelength lamda_(0) is produced at point A (Pulse 2) without disturbing the position of M it takes time T_(AO) to reach point O. Which of the following options is/are correct?
