Question

And also this,
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

speed propagation of a wave can be found by;

$|v|=\sqrt\frac{F_t}{\mu}$

where $F_r$ is tension in the string while $\mu$ is the mass per length of the string.

$|v|=\sqrt\frac{120}{3\times10^{-2}}=632.46m/s$
