Question

A sonometer wire is under a tension of 10N and length between the bridges is 2m A metre long wire of sonometer has mass 1gm Deduce the speed of transverse wave

Answer 1

Answer:

Speed of the transverse wave in the string is 100 m/s

Explanation:

As we know that the speed of transverse wave in a stretched string is given as

$v = \sqrt{\frac{T}{\mu}}$

here we know that

$T = 10 N$

$\mu$ = mass per unit length of wire

$\mu = \frac{1 \times 10^{-3}}{1}$

so we have

$v = \sqrt{\frac{10}{10^{-3}}}$

$v = 100 m/s$
