एक बंद आर्गन पाइप की मूलभूत आवृत्ति \(1.5\, kHz\) है। इस आर्गन पाइप के साथ एक व्यक्ति द्वारा स्पष्ट रूप से सुने जा सकने वाले अधिस्वरकों की संख्या है (माना व्यक्ति द्वारा सुनी जा सकने वाली अधिकतम आवृत्ति \(20,000\, Hz\) होती है)

A \(6\)
B \(4\)
C \(7\)
D \(5\)

Verified Solution

Answer & Solution

Correct Answer

(A) \(6\)

Step-by-step Solution

Detailed explanation

For closed organ pipe, resonate frequency is odd multiple of fundamental frequency. \((2 n+1) f_{o} \leq 20,000\) \(\left(f_{o} \text { is fundamental frequency }=1.5 Khz \right)\) \(n=6\)

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
