In an experiment for the determination of the speed of sound in air using the resonance method, the length of the air column that resonates in the fundamental mode with a tuning fork is $0.1 m$ . When this length is changed to $0.35 m$ , the same tuning fork resonates with the first overtone. The end correction is

Options:

Answer:

Solution:

$\frac{λ}{4} = e + l_{1}$

$\frac{3 λ}{4} = e + l_{2}$

$e + l_{2} = 3 e + 3 l_{1}$

$e = \frac{l_{2} - 3 l_{1}}{2} = \frac{0.35 - 0.3}{2} = \frac{0.05}{2} = 0.025 m$
