Question

In the experiment for the determination of the speed of sound in air using the resonance column, the 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.

Let ∆ l be the end correction. Given that, Fundamental tone for a length 0 . 1 m = first overtone for the length 0 . 35 m ∴ v 4 0.1 + ∆ l = 3 v 4 0.35 + ∆ l Solving this equations we get ∆ l = 0 . 025 m = 2 . 5 cm
