If two sine waves of the same frequency have a phase difference of JT radians, then_______?
Correct answer: C. when one wave reaches its maxi¬mum value, the other will reach its minimum value
- A. both will reach their minimum values at the same instant
- B. both will reach their maximum values at the same instant
- C. when one wave reaches its maxi¬mum value, the other will reach its minimum value
- D. none of the above
Explanation
A phase difference of \(\pi\) radians equals 180°, so the waves are oppositely phased. Consequently, whenever one reaches its maximum, the other reaches its minimum.
