In the context of physics, particularly in wave mechanics and acoustics, a "node" refers to a point along a standing wave where the wave has minimal or zero amplitude. This means that at a node, the medium through which the wave is traveling experiences no displacement. Standing waves are formed by the interference of two waves traveling in opposite directions, resulting in a pattern where certain points (nodes) experience destructive interference while other points (antinodes) experience constructive interference.
