1.	A tuning fork of frequency n resonates with a closed organ pipe when the length of the shortest air columns are a and b respectively, then the speed of sound in air will beA. n(a-b)B. `(n(b-a))/(2)`C. `2n(b+a)`D. 2n(b-a)
Answer» Correct Answer - D The first resonating length is `lamda/4 = a+e` The second resonating length is `(3lamda)/(4) = b+e` `b-a = lamda/2 therefore lamda = 2(b-a)` As `v=nlamda =2n(b-a)`
