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 λ 0 is produced at point O on the rope. The pulse takes time T O A to reach point A. If the wave pulse of wavelength λ 0 is produced at point A (Pulse 2) without disturbing the position of M it takes time T O A to reach point O. Which of the following options is/are correct?

TestHub · Accepted Answer

(i) Speed of wave is property of medium so time taken to cross the string will be equal

(ii) Speeds are same but velocity is vector, has opposite directions

(iii) Wavelength $λ = \frac{v}{f} = \frac{1}{f} \sqrt{\frac{T}{μ}}$ and $T_{0} > T_{A}$

(iv) Velocity of any pulse is $v = \sqrt{\frac{T}{μ}}$ and it is property of medium.
