Nodes and antinodes


Sources that produce waves of the same frequency and have a constant phase difference are called coherent sources.

Points of constructive interference are called antinodes (purple point) . The imaginary lines that connect the antinodes are called antinodal line. ( purple lines)

Points of destructive interference are called nodes. (blue point), whereas the nodes are connected by the nodal lines. (blue lines)
