Question

A guitar string is 0.620m long, and oscillates at 234Hz. What is the velocity of the waves in the string? m/s

Answer 1

290.16

Step-by-step explanation:

i got it right

Answer 2

v = 72.54 m/s

Step-by-step explanation:

We have,

Length of a guitar string is 0.62 m

Frequency of a guitar string is 234 Hz

For guitar string,

`L=2\lambda\\\\\lambda=(L)/(2)\\\\\lambda=(0.62)/(2)\\\\\lambda=0.31\ m`

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

`v=f\lambda\\\\v=234* 0.31\\\\v=72.54\ m/s`

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