Question

an organ pipe whcih is open at both ends resonates at its fundamental frequency. Neglecting any end effects, what wavelength is formed by this pipe in this mode of vibration if the pipe is 2 meters long?​

Answer 1

Answer:

For closed organ pipe, frequency of the fundamental note

ν

0c

​

=

4l

v

​

, where v is velocity of sound and l is the length of the pipe.

For open organ pipe, frequency of the fundamental note

ν

0o
