If the length of an open organ pipe is 33.3 ~cm , then the frequency of fifth overtone is [Neglect end correction, velocity of sound =333 ~m / s ]

Options

  1. A3500 ~Hz
  2. B3000 ~Hz
  3. C2500 ~Hz
  4. D2000 ~Hz

Correct answer

B. 3000 ~Hz

Step-by-step solution

For a pipe open at both ends, n = v 2 l = 333 2 33.3 10⁻² =500 ~Hz Frequency of 5^ th overtone, n =6 n =6 500=3000 ~Hz
