Question

an open and closed organ pipe have the same length the ratio of pth mode of frequency of vibration of two pipes is

please answer fast ​

Answer 1

Answer:

Fundamental frequency of open organ pipe is 250 Hz. Third harmonic of closed organ pipe is equal to second harmonic of open organ pipe.

Answer 2

For closed pipe, p

th

mode frequency is:

ν

cp

=

4l

v

(2p−1)

For open pipe, p

th

mode frequency is:

ν

op

=

2l

v

p

Thus,

ν

cp

ν

op

=

2p−1
