Two open pipes of different lengths and of same diameter in which the air column vibrates with fundamental frequencies ‘ $n_{1}$ ’, and ‘ $n_{2}$ ’ respectively. When both pipes are joined to form a single pipe, its fundamental frequency will be

Options:

Answer:

Solution:

$n_{1} = \frac{v}{2 l_{1}}; n_{2} = \frac{v}{2 l_{2}}$
$∴ n = \frac{v}{2 (r + l_{2})} = \frac{v}{2 r + 2 l_{2}}$
$n = \frac{v}{\frac{v}{n_{1}} + \frac{v}{n_{2}}} = \frac{n_{1} n_{2}}{n_{1} + n_{2}}$
