A) 80 Hz
B) 240 Hz
C) 320 Hz
D) 400 Hz
Correct Answer: C
Solution :
: Fundamental frequency of closed pipe \[n=\frac{v}{4l}\] \[\therefore \] \[n=\frac{320}{4\times 1}=80\,Hz\] Harmonics have frequencies 3n, 5n, .......odd n. Even multiples of fundamental (80 Hz) are not present. \[\therefore \]\[80\times 4=320\text{ }Hz\] is not present. The pipe cannot resonate for 320 Hz.You need to login to perform this action.
