A standing wave propagating with velocity $300 m s^{- 1}$ in an open pipe of length $4 m$ has four nodes. The frequency of the wave is

Options:

Answer:

Solution:

Nodes are produced in the open pipe as shown in figure.

So, $2 λ = 4$

$λ = \frac{4}{2} = 2 m$

From the wave equation,

$v = n λ$

$n = \frac{v}{λ}$

$= \frac{300}{2}$

$= 150 Hz$
