A closed organ pipe (closed at one end) is excited to support the third overtone. It is found that air in the pipe has (A) three nodes and three antinodes (B) three nodes and four antinodes (C) four nodes and three antinodes (D) four nodes and four antinodes

Third overtone has a frequency 4n, 4 textth harmonic = three full loops + one half loop, which would make four nodes and four antinodes.

three nodes and three antinodes

three nodes and four antinodes

four nodes and three antinodes

four nodes and four antinodes

Third overtone has a frequency $4 n$ , $4^{th}$ harmonic = three full loops $+$ one half loop, which would make four nodes and four antinodes.
