In a pipe closed at one end, air column is vibrating in the fourth overtone, so the vibrating air column has

Options

  1. A4 nodes and 5 antinodes.
  2. B5 nodes and 4 antinodes.
  3. C5 nodes and 5 antinodes.
  4. D4 nodes and 4 antinodes.

Correct answer

C. 5 nodes and 5 antinodes.

Step-by-step solution

For a pipe with one closed end: Fundamental mode has one node and one antinode. First overtone has two nodes and two antinodes. Second overtone has three nodes and three antinodes. So, the fifth overtone has five nodes and five antinodes.
