The fuzziness is the area of the standing wave in which the vibrations have the greatest amplitude . The opposite of an antinode is a node — a section of a wave in which the amplitude of oscillation is minimal.
The cause of the antinode is the addition of the incident and reflected coherent waves in the "phase", the node - the addition of coherent waves in the "antiphase". When two signals of similar frequency and amplitude are superposed, antinodes and constrictions are also formed.
In nature, antinodes are observed in resonators, waveguides [1] , the propagation of sound waves, and waves on the surface of water.
