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 $\lambda_0$ is produced at point A (Pulse 2 ) without disturbing the position of M it takes time $\mathrm{T}_{\mathrm{AO}}$ to reach point O . Which of the following options is/are correct?

Select ALL correct options:

A

The velocities of the two pulses (Pulse 1 and Pulse 2 ) are the same at the midpoint of rope

B

The velocities of any pulse along the rope is independent of its frequency and wavelength

C

The wavelength of Pulse 1 becomes longer when it reaches point A

D

The time $T_{A O}=T_{O A}$
