Question

A pipe open at one end has length 0.8 m . At the open end of the tube a string 0.5 m long is vibrating in its 1 st overtone and resonates with fundamental frequency of pipe. If tension in the string is 50 N , the mass of string is (speed of sound = 320 m / s )

2 × [ 2 ℓ 1 ​ 1 ​ m T ​ ​ ] = 4 ℓ 2 ​ v ​ 0.5 1 ​ m 50 ​ ​ = 4 × 0.8 320 ​ ∴ Total mass of the string = 0.02 × 0.5 kg = 10 gm ∴ 02 kg / m
