A) 80 Hz
B) 240 Hz
C) 320 Hz
D) 400 Hz
E) 560 Hz
Correct Answer: C
Solution :
Fundamental frequency \[{{f}_{0}}=\frac{v}{4L}\] \[=\frac{320}{4\times 1}=80\,Hz\] So, it can resonate with\[{{f}_{0}},3{{f}_{0}},5{{f}_{0}},7{{f}_{0}}\] \[\therefore \]Cannot resonate with 320 Hz.You need to login to perform this action.
