- A \(\frac{\mathrm{V}}{2 \mathrm{~L}}\) and all harmonics are present.
- B \(\frac{\mathrm{V}}{4 \mathrm{~L}}\) and all harmonics are present.
- C \(\frac{\mathrm{V}}{2 \mathrm{~L}}\) and even harmonics are present.
- D \(\frac{\mathrm{V}}{4 \mathrm{~L}}\) and even harmonics are present.
Answer & Solution
Correct Answer
(A) \(\frac{\mathrm{V}}{2 \mathrm{~L}}\) and all harmonics are present.
Step-by-step Solution
Detailed explanation
For an open end organ pipe, the fundamental frequency is \(f_1 = \frac{V}{2L}\). In an open end organ pipe, all harmonics are present.
