NEET (UG) 2023 — Question 31

The ratio of frequencies of fundamental harmonic produced by an open pipe to that of closed pipe having the same length is :

  1. Option A:

    2:12: 1

    Correct
  2. Option B:

    1:31: 3

  3. Option C:

    3:13: 1

  4. Option D:

    1:21: 2

Answer: A

Step-by-step solution

& f_0=f_{\text {open pipe }}=\frac{v}{2 l} \\ & f_c=f_{\text {closed pipe }}=\frac{v}{4 l} \\ & \frac{f_0}{f_c}=\frac{v}{2 l} \times \frac{4 l}{v} \\ & f_0: f_c=2: 1 \end{aligned}$$
