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

Answer

B

Explanation

Let e be the end correction then according to the given situation
`(v)/(4(l_(1) + e)) = (3v)/(4(l_(2) + e))`
e = 2.5 cm = 0.025 m.
