A) 75 Hz.
B) 225 Hz.
C) 300 Hz.
D) 375 Hz.
Correct Answer: C
Solution :
The tube will resonate for \[\ell =(2n+1)\frac{\lambda }{4},n=0,1,\,2\] Frequency \[=f=\frac{V}{\lambda }=\frac{V(2n+1)}{4\ell }=\frac{300(2n+1)}{4\times 1}\] \[=75\,(2n+1)\] For \[r=300\,Hz,\] the value of\[n=\frac{3}{2},\] which is not an integer Hence, the correction option is [c].You need to login to perform this action.
