antinode

physics
Also known as: antinodal point

Quick Summary

An antinode is a point of maximum amplitude in a standing wave. Standing waves are formed when two identical waves travel in opposite directions and interfere with each other.123

In a standing wave, there are also points called nodes, where there is no movement. Between adjacent nodes are antinodes, which represent the regions of greatest oscillation. This phenomenon is observed in various physical systems, including vibrating strings and air columns, and is fundamental to the operation of musical instruments.213
