If ' $l$ ' is the length of the open pipe, ' $r$ ' is the internal radius of the pipe and ' $V$ ' is the velocity of sound in air then fundamental frequency of open pipe is

Options:

Answer:

Solution:

For an open organ pipe, the length of the pipe with end correction is given as: $L = l + 2 e = l + 2 \times 0.6 r L = l + 1.2 r$ $∴$ The fundamental frequency of open pipe is: $f = \frac{v}{2 L} f = \frac{v}{2 ( l + 1.2 r )}$
