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

Options

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

Answer

B

Explanation

Let x the end correction then accoeding to question.
`(v)/(4(l_1+x))=(3v)/(4(l_2+x))impliesx=2.5cm=0.025m`.
