Two waves are represented by the equations y₁=a ( t+k x+0.57) m and y₂=a ( t+k x) m , where x is in metre and t in second. The phase difference between them is

Options

  1. A1.25 rad
  2. B1.57 rad
  3. C0.57 rad
  4. D1.0 rad

Correct answer

D. 1.0 rad

Step-by-step solution

y₁=a ( t+k x+0.57) m and y₂=a ( t+k x) m or y₂=a ( 2 + t+k x ) m Phase difference aligned & = ₂- ₁ & = 2 -0.57=1.57-0.57 & =1 rad aligned
