A pipe opened at both ends prpduces a note of
frequency `f_(1)`. When the pipe is kept with `3/4th` of its
length in water, it produces a note of frequency `f_(2)`.
The ratio `f_(1)/f_(2)` is

A pipe open at both produces a note of fundamental frequency v_(1) When the pipe is kept with 3/4 th of its length in water, it produces a note of fundamental frequency v_(2) The ratio of v_(1)/v_(2) is

An open organ pipe produces its fundamdental frequency f. When the pipe is dipped in water so that (2)/(5) of its length is under water, then its fundamental frequency becomes

An open organ pipe produces its fundamdental frequency f. When the pipe is dipped in water so that (2)/(5) of its length is under water, then its fundamental frequency becomes

A pipe open at both ends has a fundamental frequency f in air. The pipe is dipped vertically in water so that half of it is in water. The fundamental frequency of the air column is now :

A pipe open at both ends has a fundamental frequency f in air. The pipe is dipped vertically in water so that half of it is in water. The fundamental frequency of the air column is now :

In a pipe open at both ends the fundamental note is produced-when its length is equal to
