Question

Helpp me pleassee....

Answer 1

The fundamental wavelength of the vibrating string is 1.7 m.

Step-by-step explanation:

We have,

Velocity of wave on a guitar string is 344 m/s

Length of the guitar string is 85 cm or 0.85 m

It is required to find the fundamental wavelength of the vibrating string. The fundamental frequency on the string is given by :

`f=(v)/(2l)\\\\f=(344)/(2* 0.85)\\\\f=202.35\ Hz`

Now fundamental wavelength is :

`\lambda=(v)/(f)\\\\\lambda=(344)/(202.35)\\\\\lambda=1.7\ m`

So, the fundamental wavelength of the vibrating string is 1.7 m.
