Describe the nature of standing (stationary) waves.

Students should consider energy transfer, amplitude and phase Explain the formation of one‑dimensional standing waves

EQUALS

COMBINED:

Students should understand what is meant by nodes and antinodes.

The nodes are at either end and in the middle; the antinodes between them.

Discuss the modes of vibration of strings and air in open and in closed pipes. The lowest-frequency mode is known either as the fundamental or as the first harmonic. The term overtone will not be used.
