Organ Pipes & Resonance Tube

The fundamental frequency of an air column in a pipe closed at one end is 150 Hz. If the same pipe is open at both the end, the frequencies produced in Hz are

Show answer and solution

Answer: (d)

Closed: $\frac{v}{4L}=150\text{ Hz}$ , so open: $\frac{v}{2L}=300\text{ Hz}$ .
Open pipe gives all harmonics: $300, 600, 900, 1200 \ldots$
So the answer is (d).
