Editing Phonons (section)

=== Sound and Phonons ===
* '''[[Sound]]''': Sound is a mechanical wave that propagates through a medium (such as air, water, or solids) via pressure waves. The perception of sound is closely related to the vibrations and waves at the atomic and molecular level.
* '''[[Phonons]]''': In solids, phonons represent the quantized vibrations of atoms within a crystal lattice. Phonons are the carriers of sound at the microscopic level and play a critical role in the propagation of thermal energy and sound through materials.
