A) 0.4 m from the open end
B) 0.4 m from the closed end
C) Both (a) and (b)
D) 0.8 m from the open end
Correct Answer: A
Solution :
In first overtone mode \[l=\frac{3\lambda }{4}\] \[\therefore \] \[\frac{\lambda }{4}=\frac{l}{3}\] \[=\frac{1.2}{3}=0.4m\] Pressure variation will be maximum at displacement nodes, ie, at 0.4 m from the open end.You need to login to perform this action.
