Organ Pipes & Resonance Tube

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 $= 330\text{ m/s})($ Neglect end correction)

Show answer and solution

Answer: (b)

Fundamental $n=\frac{v}{2L}=\frac{330}{2\times0.6}=275\text{ Hz}$ .
$\frac{2200}{275}=8$
So it is the eighth harmonic: answer (b).
