Consider two identical tubes $A$ and $B$ . Tube $A$ has both ends open while tube $B$ has one end closed. The ratio of the fundamental frequency of tube $A$ and $B$ is

Options:

Answer:

Solution:

In tube $A$ , $λ_{A} = 2 l$

In tube $B$ , $λ_{B} = 4 l$

$∴$ $υ_{A} = \frac{ν}{λ_{A}} = \frac{ν}{2 l}$

$∴$ $υ_{B} = \frac{ν}{λ_{B}} = \frac{ν}{4 l}$

$∴$ $\frac{υ_{A}}{υ_{B}} = \frac{2}{1}$ .
