Vedclass · Answer

(N/A) In a stationary wave,nodes and antinodes are specific points defined by their displacement amplitude:
$1$. Nodes: These are the points in a stationary wave where the displacement of the medium particles is always zero. The amplitude of vibration at these points is $0$. They occur at positions where the waves interfere destructively.
$2$. Antinodes: These are the points in a stationary wave where the displacement of the medium particles is maximum. The amplitude of vibration at these points is maximum. They occur at positions where the waves interfere constructively.
