Consider the propagating sound (with velocity $330 m s^{- 1}$ ) in a pipe of length $1 .5 m$ with one end closed and the other open. The frequency associated with the fundamental mode is

Options:

Answer:

Solution:

Given,

Velocity of sound $= 330 m s^{- 1}$

Length of closed pipe $= 15 m$

In a closed pipe for the fundamental mode

$\frac{λ}{4} = l$

$λ = 4 \times 15 = 6 m$

$v = n λ$

$n = \frac{v}{λ}$

$= \frac{330}{6}$

$= 55 Hz$
