In fundamental mode, the time required for the sound wave to reach up to the closed end of a pipe ﬁlled with air is ‘ $t$ ’ second. The frequency of vibration of air column is

Options:

Answer:

Solution:

$∵ f_{0} = \frac{v}{4 l}$
$f_{0} = \frac{1}{4 l} (\frac{D i s t a n c e}{t i m e})$
$f_{0} = \frac{1}{4 l} (\frac{l}{t})$
$f_{0} = \frac{1}{4 t}$
