If speed of sound in air in 330 ~m ~s ⁻¹ , then find the number of overtones present in an open organ pipe of length 1 ~m whose frequency f 1000

Options

  1. A2
  2. B4
  3. C8
  4. D6

Correct answer

D. 6

Step-by-step solution

Fundamental frequency, aligned & v= v 2 = 330 2 1 =165 ~Hz & Number of overtones allowed = 1000 165 =6 aligned
