Question

2. Derive a formula for the speed of the wave in terms of the fundamental frequency f1 and the string length L, and enter it below.

Answer 1

Answer:

The speed of the wave is $f_{1}2L$

Explanation:

Given that,

Frequency = f

String length = l

We need to drive a formula of the speed of the wave

Using formula of fundamental frequency

$f=\dfrac{v}{\lambda}$

We know that,

$\lambda=2L$

$f=\dfrac{v}{2L}$

Where, v = speed of wave

$\lambda$ = wavelength of the wave

f = frequency

The speed of the wave is

$v=f_{1}2L$

Hence, The speed of the wave is $f_{1}2L$
