Question

A pipe closed at one end has length 0.8 m . At its open end 0.5 m long uniform string is vibrating in its 2 nd harmonic and it resonates with the fundamental frequency of the pipe. If the tension in the wire is 50 N and the speed of sound is 320 m / s , the mass of the string is

​ 2 × [ 2 ℓ 1 ​ 1 ​ m T ​ ​ ] = 4 ℓ 2 ​ v ​ 0.5 1 ​ m 50 ​ ​ = 4 × 0.8 320 ​ ∴ m = 0.02 kg / m ∴ Total mass of the string = 0.02 × 0.5 kg = 10 gm ​
