Two waves y₁=0.35 (316 t) and y₂=0.35 (310 t) are propagating along the same direction. The number of beats produced per second are

Options

  1. A3
  2. B2
  3. C2
  4. D3

Correct answer

A. 3

Step-by-step solution

According to question: f₁= 316 2 and, f₂= 310 2 Now, The number of beats heard per second =f₁-f₂= 316 2 - 310 2 = 3
