Answer :
Given that the distance between 2 consecutive nodes is 2m
We have to find the wavelength
[tex]\lambda[/tex]The distance between 2 nodes is half the wavelength,
[tex]\begin{gathered} \frac{\lambda}{2}=2 \\ \lambda=\text{ 4 m} \end{gathered}[/tex]Thus, the wavelength of the standing wave is 4 m.
