Two vibrating tuning forks produce progressive waves given Y₁=4 500 t and Y₂=2 506 t . Number of beats produced per minute is:

Options

  1. A360
  2. B180
  3. C60
  4. D3

Correct answer

B. 180

Step-by-step solution

aligned & y₁=4 500 t & y₂=2 506 t & ₁=500 , & ₂=500 , =2 & v₁=250, v₂=253 & aligned aligned v & =v₂-v₁=253-250 & =3 beats / s aligned
