Editing Transverse wave (section)

===Superposition principle===
In a [[homogeneous]] [[Linear combination|linear]] medium, complex oscillations (vibrations in a material or light flows) can be described as the [[wave superposition|superposition]] of many simple sinusoidal waves, either transverse or longitudinal.

The vibrations of a violin string create [[standing waves]],<ref>University Physics, Vol. 1, Chapter 16.6, “Standing Waves and Resonance” University of Central Florida, https://pressbooks.online.ucf.edu/osuniversityphysics/chapter/16-6-standing-waves-and-resonance/.</ref> for example, which can be analyzed as the sum of many transverse waves of different frequencies moving in opposite directions to each other, that displace the string either up or down or left to right. The [[antinodes]] of the waves align in a superposition .
