A string fixed at both ends oscillates in 5 segments, length 10 m and velocity of wave is 20 ~m / s . What is the frequency?

Options

  1. A5 Hz
  2. B15 Hz
  3. C10 Hz
  4. D2 Hz

Correct answer

A. 5 Hz

Step-by-step solution

Frequency of vibration is given by n= p 2 l T m ( where v= T m ) n= p v 2 l = 5 20 2 10 =5 ~Hz
