The displacement of two sinusoidal waves is given by the equation aligned & y₁=8 (20 x-30 t) & y₂=8 (25 x-40 t) aligned then the phase difference between the waves after time t =2 ~s and distance x =5 ~cm will be

Options

  1. A2 radian
  2. B3 radian
  3. C4 radian
  4. D5 radian

Correct answer

D. 5 radian

Step-by-step solution

y₁=8 (20 x-3 t) Substituting x=5 ~cm and t=2 ~s , y₁=8 (40) Similarly, y₂=8 (45) phase difference =45-40=5 radian
