A pipe P _ C closed at one end and pipe P _ O open at both ends are vibrating in second overtone. They are in resonance with a given tuning fork. The ratio of the length of pipe P _ C vs P _ O is (Neglect end correction)

Options

  1. A4 5
  2. B5 6
  3. C2 3
  4. D3 5

Correct answer

B. 5 6

Step-by-step solution

For second overtone: If they are in the resonance with the same tuning fork, using: f = v f and v are the same, so aligned & _C= ₀ & ( 4 5 L_C )= 2 3 L₀ & L_C L₀ = 5 6 aligned
