STANDARD Physics Phase Difference MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Two waves are represented by y₁ = a sin(ωt + kx + 0.57) and y₂ = a cos(ωt + kx). The phase difference between the two waves is:
A
1.0 radian
B
1.25 radian
C
1.57 radian
D
0.57 radian
Correct Answer
Option A
Detailed Explanation
The phase of y₁ is (ωt + kx + 0.57) and the phase of y₂ is (ωt + kx + π/2). The phase difference Δϕ = (ωt + kx + π/2) - (ωt + kx + 0.57) = π/2 - 0.57 = 1.0 radian.
