Question

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
????₀ is produced at point O on the rope. The pulse takes time Tᴏᴀ to reach point A. If the wave pulse of
wavelength ????₀ is produced at point A (Pulse 2) without disturbing the position of M it takes time Tᴀᴏ to
reach point O. Which of the following options is/are correct?
[A] The time Tᴀᴏ = Tᴏᴀ
[B] The velocities of the two pulses (Pulse 1 and Pulse 2) are the same at the midpoint of rope.
[C] The wavelength of Pulse 1 becomes longer when it reaches point A.
[D] The velocity of any pulse along the rope is independent of its frequency and wavelength.
