A pipe 60 cm long and open at both the ends produces harmonics. Which harmonic mode of pipe resonates a 2.2 KHz source? (Speed of sound in air =330 ~m / s ) (Neglect end correction)

Step-by-step solution

Here, l=60 ~cm , v=2200 ~Hz , v =330 ~m / s . If n ^ th harmonic of pipe resonates with the source, then for a open pipe, aligned v & = n v 2 l_ o 2200 & = n [ 330 2 (60 10⁻² ) ] n & = 2 (60 10⁻² ) 2200 330 =8 aligned
