The fundamental frequency of a pipe closed at one end is in unison with the third overtone of an open pipe. Calculate the ratio of their lengths of air column.

Fifth overtone of closed organ pipe is in unison with fifth overtone of open organ pipe. The ratio of their lengths is

The frequency of third overtone of a closed pipe is in unison with the fifth overtone of an open pipe .What is the ratio of their lengths ? (Neglect end correction)

The fundamental frequency of a closed pipe, if its first overtone is unison with a tuning fork of 480 Hz is

The fundamental frequency of a closed organ pipe is 50 Hz . The frequency of the second overtone is

The fundamental frequency of a closed organ pipe of length 20 cm is equal to the second overtone of an organ pipe open at both the ends. The length of organ pipe open at both the ends is

The third overtone of a closed organ pipe is found to be in unison with first overtone an open pipe. The ratio of the length of the pipe is: A. 7/4 B. 4/7 C. 1/7 D. 7/1

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

The frequency of the open organ pipe is

A pipe open at both the ends has a fundamental frequency of 600 Hz . The first overtone of a pipe closed at one end has the same frequency as the first overtone of the open pipe. How long are the two pipes ?
