Question

A transverse wave is applied to a string whose mass per unit length is 3×10 raise to power -2kgmper -1.if the string is under a tension of 120N, calculate the speed of propagation of wave?

Answer 1

Given

Linear density is $\mu=3.0\times10^{-2} kg/m$

Tension is $T=120 N$

The expression for speed of propagation of wave is

$v=\sqrt \frac{T}{\mu}= \sqrt \frac{120 N}{3.0\times10^{-2} kg/m}=63 m/s$
