If two waves with identical crests and troughs meet, then we know
that they have the same amplitude, frequency, and wavelength. 
But we still don't know whether they are "in step" or not.

If their crests of both waves line up, then constructive interference
will occur.

If the crests of one wave line up with the troughs of the other wave,
then destructive interference will occur.
