AIPMT PRELIMS 2011 Physics Phase Difference MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Two waves are represented by the equations y₁ = a sin(ωt + kx + 0.57)m and y₂ = a cos(ωt + kx)m, where x is in meter and t in s. The phase difference between them is
A
0.57 radian
B
1.0 radian
C
1.25 radian
D
1.57 radian
Correct Answer
Option B
Detailed Explanation
The phase difference between y₁ and y₂ is calculated as π/2 - 0.57 = 1 radian.
