PhysicsEasysingle choice

Tube $A$ has both ends open while tube $B$ has one end closed, otherwise they are identical. The ratio of fundamental frequency of tube $A$ and $B$ is

Options:

Answer:

Solution:

Fundamental freq. for, Tube $A \Rightarrow f_{A} = \frac{v}{2 L}$ Tube $B \Rightarrow f_{B} = \frac{v}{4 L}$ Now, $\frac{f _{A}}{f _{B}} = \frac{v}{2 L} \times \frac{4 L}{v} = \frac{2}{1} f_{A} : f_{B} = 2 : 1$
