When an air column in a pipe open at both ends vibrates such that four antinodes and three nodes are formed, then the corresponding mode of vibration is

Options

  1. Afirst overtone
  2. Bsecond overtone
  3. Cfourth overtone
  4. Dthird overtone

Correct answer

B. second overtone

Step-by-step solution

Since L = 3 2 , it is third harmonic or second overtone.
