A) 320m/s, 120 Hz
B) 180m/s, 80 Hz
C) 180m/s, 120 Hz
D) 320m/s, 80 Hz
Correct Answer: D
Solution :
\[3\left( \frac{\text{v}}{2\ell } \right)=240\] \[3\frac{\text{v}}{2\times 2}=240\] \[\text{v}=320m/s\] fundamental frequency\[=\frac{\text{v}}{2\ell }=\frac{320}{2\times 2}=80Hz.\]You need to login to perform this action.
