- In the physics of waves, an antinode is a point, line, or surface in a standing
wave where some characteristic of the wave field has maximum amplitude.
A standing, or stationary, wave is one whose shape stays the same and
that doesn't appear to move through a medium. It occurs when a traveling
wave is reflected along its own path. Antinodes and nodes are separated by a quarter of a wavelength.
AND WAVE PHENOMENA
- In celestial mechanics, an antinode is either of the two points on an orbit where a line in the orbit plane, perpendicular to the line
of nodes, and passing through the focus, intersects the orbit.
