Two waves are represented by: x 1 = A sin ω t + π 6 and x 2 = A cos ω t . Then the phase difference between them is
Options
- Aπ 6
- Bπ 3
- Cπ 2
- Dπ
Correct answer
C. π 2
Step-by-step solution
Given, x 1 = A sin ω t + π 6 and x 2 = A cos ω t x 1 can be written as x 1 = A cos π 2 - ω t - π 6 x 1 = A cos π 3 - ω t The phase difference between them = π 2
