A guitar string is 0.620 m long, and oscillates at 234 Hz. What is the
velocity of the waves in the string?
(Unit = m/s)
please help will give brainliest

Explanation:

We have,

Length of a guitar string is 0.62 m

Frequency of a guitar string is 234 Hz

For guitar string,

\begin{gathered}L=2\lambdalambda=\dfrac{L}{2}lambda=\dfrac{0.62}{2}lambda=0.31\ m\end{gathered}

L=2λ

λ=

2

L

λ=

2

0.62

λ=0.31 m

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

\begin{gathered}v=f\lambdav=234\times 0.31v=72.54\ m/s\end{gathered}

v=fλ

v=234×0.31

v=72.54 m/s

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

580.32 m/s

Explanation:

a guitar string can only make a phase of 1/4 wave, so

0.620 = ¼ wavelenght

wavelenght = 4 * 0.620 m = 2.48 m

v = wavelenght * frequency

v = 2.48 * 234 = 580.32 m/s
