Two waves Y₁=0 25 316 t and Y ₂=0 25 310 t are propagating along the same direction. The number of beats produced per second are

Options

  1. A2
  2. B2
  3. C3
  4. D3

Correct answer

D. 3

Step-by-step solution

No. of beats = n ₁- n ₂ Y ₁=0.25 316 t 2 T =316 n ₁= 316 2 Y ₂=0.25 310 t n ₂= 310 2 n ₁- n ₂= 316-310 2 = 6 2 = 3
