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 0.1 m. when this length is changed to 0.35 m, the same tuning fork resonates with the first overtone. Calculate the end correction
0.025 m
Let x be the end correction then according to question.
v4(l1+x)=3v4(l2+x)⇒x=2.5cm=0.025m.
