Physics - Wave on String Question with Solution | TestHub

The correct option is (B). If the string is clamped between two supports separated by L. For the fundamental overtone separation between successive nodes is $\mathrm{L}$. For the first overtone separation between successive nodes is $\frac{L}{2}$. For the second overtone the separation between successive nodes will be $\frac{L}{3}$. So, for nth overtone the separation between successive nodes will be $\frac{\mathrm{L}}{(\mathrm{n}+1)}$. Therefore, for the fifth over separation between successive nodes will be $\frac{\mathrm{L}}{6}$. In the separation between successive node and antinode is half of the separation between two successive nodes. So, $\frac{\mathrm{L}}{12}=\frac{2.4\mathrm{m}}{12}=0.2\mathrm{m}$
