Relating to or located at an antinode, a point of maximum vibration in a standing wave.
From anti- (opposite) + nodal (relating to nodes, from Latin nodus meaning 'knot'). Physics term formed to describe points opposite to nodes in wave patterns.
In physics, nodes are the quiet spots and antinodes are the loudest spots in a vibrating string—it's like the mosh pit versus the back row at a concert, and they switch places depending on the frequency!
