- three nodes and three antinodes.
- three nodes and four antinodes.
- two nodes and three antinodes.
- four nodes and three antinodes.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Fundamental Mode
Closed pipe: Fundamental mode has 1 Node (at closed end) and 1 Antinode (at open end).
Step 2: Overtones
- 1st Overtone (3rd Harmonic): 2 Nodes, 2 Antinodes.
- 2nd Overtone (5th Harmonic): 3 Nodes, 3 Antinodes.
Step 3: Conclusion
In the second overtone of a closed pipe, there are 3 nodes and 3 antinodes.
Final Answer: (A)
