Question
A uniform rope having some mass hanges vertically from a rigid support. A transverse wave pulse is produced at the lower end. The speed (v) of the wave pulse varies with height (h) from the lower end as:
Options
A.
B.
C.
D.
Solution
Sol. 
$v_{w} = \sqrt{\frac{T}{\mu}} = \sqrt{\frac{Mgh \times L}{L \times M}}$
$= \sqrt{gh}$
