What is the wave equation?Show answer
For any periodic wave the speed, frequency and wavelength are linked by
What are standing waves?Show answer
A standing wave forms when a wave reflects and superposes with itself in a bounded medium, producing fixed nodes (zero displacement) and antinodes (maximum displacement). Only certain wavelengths fit the boundaries, giving a discrete set of harmonics.
