For a certain organ pipe, three successive resonance frequencies are observer at `425`, `595` and `765 H_(Z)` respectively. Taking the speed of sound in air to be `340 m//s`, (a) explain whether the pipe is closed at one or open at boyh ends. (b) determine the fundamental frequency and length of the pipe.

Text Solution

Verified by Experts

The correct Answer is:
85 Hz , 1 m
As fundametal frequency is 85 Hz we use for a closed pipe
`n_(0) = (v)/(4l)`
`l = (v)/(4n_(0) = (340)/(4 xx 85)` = 1m
