The fundamental frequency of a closed organ pipe of length 20cm is equal to the 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 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

Show that in a closed end organ pipe the first three harmonics are in the ratio of 1 : 3 : 5.

Assertion : A closed pipe and an open organ pipe are of same length. Then, neither of their frequencies can be same. Reason : In the above case fundamental frequency of closed organ pipe will be two times the fundamental frequency of open organ pipe.

The fundamental frequency of an open organ pipe is 300Hz. The first overtone of this has same frequency as that of first overtone of a closed organ pipe. If speed of sound is 330m/s, then the length of closed of organ pipe will be

Derive an expression for the nth mode of vibration in case of a closed end organ pipe. Hence give the value of v_1 :v_2 :v_3 .

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

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.
