. Two waves are represented by the equations y1
y1 = asin ( ωt + kx + 0.57 )m and y2 = acos ( ωt + kx )m, where x is in metre and t in second. The phase difference between them is
A: 0.57 radian
B: 1.0 radian
C: 1.25 radian
D: 1.57 radian
Best Answer
Explanation:
The twwo waves can be written as
y1=asin(ωt+kx+0.57)
y1=acos(ωt+kx)
y1=asin(ωt+kx+0.57+π/2)
So the phase difference is
ϕ=π/2-0.57
⇒ϕ=1.57-0.57
⇒ϕ=1.00
Final Answer:
The correct option is (B).
