Question

Two waves are having a constant phase difference does it means the two waves can be out of phase 180 with respect to one another ?

Answer 1

Yes, it is possible for the two waves to be `180^@` out of phase with respect to one another.

Explanation:

The phase difference can be any amount between `0^@ and 360^@`. So yes, `180^@` is possible. That would mean they have the same frequency. However, if they are in the same space, their amplitudes would cancel each other out.

I hope this helps,
