A cylindrical tube open at both ends, has a vibrating air column of fundamental frequency ' f ' in air. The tube is dipped vertically in water so that half of its is in water. The fundamental frequency of the vibrating air column is now

TestHub · Accepted Answer

v = λ f Fundamental frequency's λ = f v ​ ⇒ f 0 ​ = 2 L v ​ = f If the tube is dipped half into liquid then it acts as if closed at 2 L ​ . See figure The frequency can be written as f c ​ = λ 1 ​ v ​ = 2 L v ​ = f ∴ Fundamental frequency would remain the same ' f '.
