A string fixed at both the ends forms standing wave with node separation of 5 ~cm . If the velocity of the wave on the string is 2 ~m / s , then the frequency of vibration of the string is

Options

  1. A0.2 ~Hz
  2. B10 ~Hz
  3. C20 ~Hz
  4. D40 ~Hz

Correct answer

C. 20 ~Hz

Step-by-step solution

Separation between consecutive nodes, 2 =5 ~cm =10 ~cm =0.1 ~m The frequency of vibration is given as: n = v = 2 0.1 =20 ~Hz
