Organ Pipes & Resonance Tube

If the length of an open organ pipe is $33.3\text{ cm}$ , then the frequency of fifth overtone is [Neglect end correction, velocity of sound $= 333\text{ m/s}$ ]

Show answer and solution

Answer: (b)

Fundamental $n=\frac{v}{2L}=\frac{333}{2\times0.333}=500\text{ Hz}$ .
Fifth overtone of an open pipe is the 6th harmonic: $6\times500$ .
$3000\text{ Hz}$ , so the answer is (b).
