Given that there is a string of length, L= 10m, and the number of nodes n= 5.
We have to find the wavelength.
As it has 5 nodes it is 5th harmonic,
So, the formula to find the wavelength of the 5th harmonic is
[tex]L=\frac{n}{2}\lambda[/tex]
Substituting the values, we get
[tex]\begin{gathered} \lambda=\frac{2L}{n} \\ =\frac{2\times10}{5} \\ =4\text{ m} \end{gathered}[/tex]
Thus, the wavelength of the wave is 4 m
