List-I represents the standing waves in air columns and string. List-II represents frequency of the note. Match List-I with List-II. [ v = velocity of sound in the medium] List - I List - II (P) 2nd h

Question

List-I represents the standing waves in air columns and string. List-II represents frequency of the note. Match List-I with List-II. [ $v$ = velocity of sound in the medium]

List - I	List - II
(P) 2nd harmonic, tube open at both ends	(1) $\frac{v}{4 ℓ}$
(Q) fundamental, tube closed at one end	(2) $\frac{v}{2 ℓ}$
(R) 1st overtone, tube closed at one end	(3) $\frac{3 v}{4 ℓ}$
(S) fundamental, string fixed at both ends	(4) $\frac{v}{ℓ}$
	(5) $\frac{5 v}{4 ℓ}$

TestHub · Accepted Answer

Open-open 2nd harmonic: 2 ⋅ 2 ℓ v ​ = ℓ v ​ , so P → 4 . Closed-end fundamental: 4 ℓ v ​ , so Q → 1 ; closed-end 1st overtone: 4 ℓ 3 v ​ , so R → 3 . String fixed at both ends, fundamental: 2 ℓ v ​ , so S → 2 . Option (B).
