Two sound waves having frequencies 250 Hz and 256 Hz superimpose to produce beat wave. The resultant beat wave has intensity maximum at t=0 . After how much time an intensity will be minimum produced at the same point?

Options

  1. A1 6 ~s
  2. B1 24 ~s
  3. C1 18 ~s
  4. D1 12 ~s

Correct answer

D. 1 12 ~s

Step-by-step solution

Beat frequency =256-250=6 ~Hz Time between the maxima and minima of the beats is T_ beats 2 . T _ beats 2 = 1 6 2 = 1 12 ~s
