Organ Pipes & Resonance Tube

The fundamental frequencies of vibrations of air column in pipe open at both ends and in pipe closed at one end are ' $n_1$ ' and ' $n_2$ ' respectively, then

Show answer and solution

Answer: (b)

For the same length: $n_1=\frac{v}{2L}$ , $n_2=\frac{v}{4L}$ .
$n_1=2n_2$ , so the answer is (b).
