A pipe with 30 cm Length is open at both ends, which harmonic mode of the pipe resonates a 1.65 kHz source? (Velocity of sound in air =330 ~ms ⁻¹ )

Options

  1. A2
  2. B3
  3. C3.5
  4. D2.5

Correct answer

B. 3

Step-by-step solution

For open organ pipe, aligned & l =30 ~cm , f =1.65 KHz & I = n 2 n = 21 v f = 2 30 10⁻² 1.65 10^3 330 & n =3 aligned
