1. a point of maximum amplitude in a standing wave pattern where vibrations are strongest
Usage: physics; acoustics

Examples

• The guitar string vibrated most strongly at the antinode.
• Sound waves create antinodes where the amplitude is greatest.
• In the standing wave pattern, antinodes appeared between the nodes.
• The physicist measured the distance between consecutive antinodes.
• At the antinode, the wave displacement reached its maximum value.
• The microphone detected the loudest sound at each antinode position.
