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

Question

Infinity Learn · Accepted Answer

Let x be the end correction then according to question.$$v4(l1+x)$$ $$=$$ $$3v4(l2+x)$$   ⇒ x $$=$$ $$2.5$$ cm $$=$$ $$0.025$$ m
