In a resonance pipe the first and second resonances are obtained at depths 22.7 ~cm and 70.2 ~cm respectively. What will be the end correction ?

Options

  1. A1.05 ~cm
  2. B115.5 ~cm
  3. C92.5 ~cm
  4. D113.5 ~cm

Correct answer

A. 1.05 ~cm

Step-by-step solution

For end correction x , l₂+x l₁+x = 3 / 4 / 4 =3 aligned x &= l₂-3 l₁ 2 &= 70.2-3 22.7 2 =1.05 ~cm aligned
