PhysicsEasysingle choice

A closed organ pipe and an open organ pipe are tuned to the same fundamental frequency. The ratio of their lengths is

Options:

Answer:

Solution:

Fundamental frequency of close pipe,

$v_{1} = \frac{v}{4 l_{1}}$

Fundamental frequency of open pipe,

$v_{2} = \frac{v}{2 l_{2}}$

But $v_{1} = v_{2}$

$∴ \frac{l_{1}}{l_{2}} = \frac{1}{2}$
