What is organ pipe ?

An open organ pipe and a closed organ pipe are tuned to the same fundamental wavelength. What is the ratio of their lengths ?

The fundamental frequency in an open organ pipe is equal to the third harmonic of a closed organ pipe. If the length of the closed organ pipe is 20 cm, the length of the open organ pipe is

If the frequency of the first overtone of a closed organ pipe of length 33 cm is equal to the frequency of the first overtone of an open organ pipe, then the length of the open organ pipe will be

The frequency of the open organ pipe is

A closed organ pipe and an open organ pipe have their first overtones identical in frequency . Their lenghts are in the ratio

A closed organ pipe and an open organ pipe are tuned to the same fundamental frequency. The ratio of their lengths is

Assertion: The fundamental frequency of vibration of an open organ pipe remains same if the radius of the pipe is doubled. Reason: Frequency of vibration of an open organ pipe is independent of the radius of pipe.

The lengths of an open organ pipe is twice the length of another closed organ pipe. The fundamental frequency of the open pipe is 100 Hz. The freqeuncy of the third harmonic of the closed pipe is

The fundamental note produced by a closed organ pipe is of frequency v. The fundamental note produced by an open organ pipe of same length will be of frequency

For a certain organ pipe , three successive resonance frquencies are observed at 170 Hz , 255 Hz and 340 Hz respectively then the pipe is
