The fundamental frequency of a closed pipe is equal to the frequency of the second harmonic of an open pipe. The ratio of their lengths is

Answer»

`1:2`
`1:4`
`1:8`
`1:16`

SOLUTION :For closed pipe, fundamental frequency is,
`f_(1) =v/(4l)`
For OPEN pipe, frequency of second harmonic
`f_(2) =v/L`
ACCORDING to question, `f_(1) =f_(2)`
`v/(4l) =v/L` or `l/L =1/4`
