Meaning and Definition
A point of maximum amplitude in a standing wave system.
In physics, a point in a standing wave where the oscillation is at its greatest amplitude; conceptually, a point of concentrated effect or activity in a pattern of opposing forces or oscillations.

FAQ
Frequently Asked Questions
No, it is a highly specialised term used almost exclusively in physics and related engineering fields.
Very rarely and only in highly stylised or academic (non-scientific) writing. Its standard use is strictly technical.
They are opposites in a standing wave. A node is a point of minimal or zero amplitude (stillness), while an antinode is a point of maximum amplitude (greatest movement). They alternate along the wave.
The most common pronunciation is /ˈæntiˌnoʊd/ (AN-tee-node). A less common variant is /ˈænˌtaɪˌnoʊd/ (AN-tie-node).
A point of maximum amplitude in a standing wave system.
Antinode is usually technical/scientific in register.
Learning
Memory Aids
Mnemonic
ANTI-NODE: Think 'ANTI-node' as the opposite of a quiet node; it's the ANTI-thesis of stillness, where the wave activity is TIPTOE-ing at its maximum height.
Conceptual Metaphor
A point of intense activity or focus within a system of conflicting/oscillating forces (e.g., 'He was the antinode of the political debate').
