8.1.3—The formation of a stationary wave using a graphical method, and identify

A stationary wave results when two coherent waves of the same frequency, speed and amplitude travel in opposite directions and superpose.

The pattern has fixed nodes and antinodes, so there is no net energy transfer along the medium even though particles oscillate between them.

A string driven at one end and reflected at the other can settle into a pattern with several loops separated by nodes.

A stationary wave is not a wave travelling slowly; its nodes remain fixed while local oscillations continue.
