When open pipe is closed from one end, then third overtone of closed pipe is higher in frequency by 150 Hz than second overtone of open pipe. The fundamental frequency of open end pipe will be

A

75 Hz

B

150 Hz

C

225 Hz

D

300 Hz

Text Solution

Verified by Experts

The correct Answer is:
D
`n_(3)-n_(2)=150`
`7n_(c)-3n_(0)=150`
`7n_(c)-3xxn_(0)=150`
`7n_(c)-6n_(c)=150`
`n_(c)=150`
But, `n_(0)=2n_(c)`
`:.n_(0)=2xx150=300Hz.`
