Question

a closed organ Pipe and an open organ pipe a tuned to the same fundamental frequency the ratio of the length is​

Answer 1

A closed cylindrical air column will produce resonant standing waves at a fundamental frequency and at odd harmonics. The closed end is constrained to be a node of the wave and the open end is of course an antinode. This makes the fundamental mode such that the wavelength is four times the length of the air column.

Answer 2

Answer:

1:2

Explanation:

for a closed pipe, the fundamental frequency is V/4Lc

for an open pipe , the fundamental frequency is  V/2Lo

it is given that they are having same fundamental frequency.

then , V/4Lc = V/2Lo

        Lc / Lo = 2 / 4 = 1 / 2

so the ratio of their length is 1:2.
