Question

An open pipe is suddenly closed at one end with the result that the frequncy of third harmonic of the closed pipe is found to be higher by 100 Hz than the fundamental frequency of the open pipe. The fundamental frequncy of the open pipe is

Accepted Answer

Length of organ pipe is same in both the case. Fundamental frequency of open is f₁ =

and Frequency of third harmonic of closed pipe will be f₂ = 3

Given that, f₂ = f₁ + 100
or f₂ - f₁ = 100
or

∴

or f₁ = 200Hz.
Therefore, fundamental frequency of the open pipe is 200 Hz.
