Superposition and stationary waves

Superposition and stationary waves

Three-panel diagram showing a right-moving wave, a left-moving wave, and the resulting stationary wave with nodes and antinodes labelled.

When two waves overlap, the principle of superposition says that the resultant displacement is the algebraic sum of the individual displacements at that point, so y=y1+y2y = y_1 + y_2y=y1​+y2​.
