A string is vibrating in its fifth overtone between two rigid supports 2.4 m apart. The distance between successive node and antinode is

Options

  1. A0.1 m
  2. B0.2 m
  3. C0.6 m
  4. D0.8 m

Correct answer

B. 0.2 m

Step-by-step solution

Fifth overtone = Sixth harmonic 2.4 = 6 λ 2 λ 2 = 0.4 m λ 2 = 0.4 λ = 0.8 λ 4 = 0.8 4 = 0.2 m
