When a stretched wire of fundamental frequency f is divided into three segments, the fundamental frequencies of these three segments are f₁, f₂ and f₃ respectively. Then the relation among f ₁, f ₂, f ₃ and f is (Assume tension is constant)

Options

  1. Af = f ₁ + f ₂ + f ₃
  2. Bf = f ₁+ f ₂+ f ₃
  3. C1 f = 1 f ₁ + 1 f ₂ + 1 f ₃
  4. D1 f = 1 f ₁ + 1 f ₂ + 1 f ₃

Correct answer

C. 1 f = 1 f ₁ + 1 f ₂ + 1 f ₃
