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

In an open organ pipe, if the fundamental frequency is n, the overtones produced in it are in the ratio of-

The first overtone in a closed pipe has a frequency

Compare the length of a closed organ pipe and an open organ pipe, if the second overtone of the open pipe is unison with the second overtone of the closed organ pipe.

In open organ pipe, first overtone produced is of such frequency that length of the pipe is equal to

The frequency of open organ pipe is

The fimdamental frequency of a closed organ pipe is equal to second of an open organ pipe is the length of closed organ pipe is 15 cm. The length of open organ pipe is
