Question

In an experiment for the determination of the speed of sound in air using 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. Calculate the end correction –

• A. 0.012 m
• B. 0.025 m
• C. 0.05 m
• D. 0.024 m

Answer 1

Answer: (B)

0.025 m

Answer 2

l = $\frac { \ell _ { 2 } - 3 \ell _ { 1 } } { 2 }$ = = $\frac { 0.05 } { 2 }$ = 0.025 m
