A) 300 m/s
B) 350 m/s
C) 340 m/s
D) 330 m/s
Correct Answer: C
Solution :
The relation between distance of successive nodes and wavelength of the wave is \[s=85=\frac{(n-1)\lambda }{2}=\frac{(6-1)\lambda }{2}=\frac{5\lambda }{2}\] \[\Rightarrow \] \[\lambda =\frac{85\times 2}{5}=34\,cm=0.34\,m\] Speed of sound \[v=f\lambda ,\]where\[f\]is frequency and \[\lambda \]is wavelength. \[v=1000\times 0.34\,=340\,m/s\]You need to login to perform this action.
