A) \[1000\,\,m/s\]
B) \[25\,\,m/s\]
C) \[100\,\,cm\]
D) \[10\,\,cm\]
Correct Answer: C
Solution :
The first overtone of a wave on string is given by \[n=\frac{v}{\lambda }\] where \[1\] is wavelength, \[v\] the velocity and \[n\] the frequency. Given, \[\lambda =l\] (in first overtone) \[\therefore \] \[n=\frac{v}{l}\] \[\Rightarrow \] \[v=nl=250\times 2=500\,\,m/s\]You need to login to perform this action.
