Question

A uniform rope having mass m hangs vertically from a rigid support. A transverse wave pulse is produced at the lower end. The speed n of wave pulse varies with height h from the lower end as –

• A. ```````
• B.
• C.
• D.

Answer 1

Answer: (C)

Answer 2

V = $\sqrt{xg}$ or V = $\sqrt{gh}$

'h' ® distance form lower end

So $\begin{matrix} V^{2} \propto h \end{matrix}$ parabola
