A block M hangs from the bottom of a uniform rope whose top is fixed at O. A pulse of wavelength λ₀ travels from O to A in time Tₒₐ. An identical pulse launched from A travels to O in time Tₐₒ. Which statement(s) are correct?

Step 1: Local transverse-wave speed is v = √(T/μ). Step 2: If T varies with position, use dt = dx/v and integrate; otherwise use time = length/speed. Step 3: Use force balance to obtain the required tension where needed. Final: A: Tₐₒ = Tₒₐ; D: Pulse speed along the rope is independent of pulse frequency and wavelength..
