Answer:

v = 72.54 m/s

Explanation:

We have,

Length of a guitar string is 0.62 m

Frequency of a guitar string is 234 Hz

For guitar string,

[tex]L=2\lambda\\\\\lambda=\dfrac{L}{2}\\\\\lambda=\dfrac{0.62}{2}\\\\\lambda=0.31\ m[/tex]

The velocity of the wave in the string is given by :

[tex]v=f\lambda\\\\v=234\times 0.31\\\\v=72.54\ m/s[/tex]

So, the velocity of the waves in the string is 72.54 m/s.
