  • When connected to the speakers, the two sound waves operated in antiphase, causing a noticeable drop in volume.

Examples

  • In the experiment, we observed that the two waveforms interacted in an antiphase relationship, leading to a dramatic reduction in amplitude.

  • These events are identified in the N hemispheric records (particularly high latitudes), whereas the S hemisphere response has been muted and, on detailed inspection, clearly responds in an antiphase manner with respect to changes in the N hemisphere.

Morphology

antiphase = phase (semi-transparent) = anti + phase

The parts clearly mean 'opposite phase', but the term is technical and the full scientific use is not fully obvious to all learners.

Etymology

Antiphase comes from anti- 'against' and phase 'stage' or 'part of a wave'. So, when two waves are antiphase, they are 'against' each other — one wave's high meets the other's low and they cancel each other out, which is why the word describes things that are exactly out of step.
