A) 1000 m/s
B) 25 m/s
C) 500 m/s
D) 10 m/s
Correct Answer: C
Solution :
The first overtone of a wave on string is given by \[n=\frac{v}{\lambda }\] where\[\lambda \] 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.
