A) 125.00
B) 93.75
C) 62.50
D) 187.50
Correct Answer: B
Solution :
Given : Frequency of tuning fork, \[n=264Hz\] Length of column L= ? For closed organ pipe\[n=\frac{v}{4l}\] \[\Rightarrow \]\[l=\frac{v}{4n}=\frac{330}{4\times 264}=0.125\]or\[l=0.3125\times 100=31.25cm\]In case of closed organ pipe only odd harmonics are possible. Therefore value of \[l\] will be \[(2n-1)l\] Hence option (b) i.e. \[3\times 31.25=93.75cm\]is correct.You need to login to perform this action.
