WebCheck Your Understanding 16.1. When a guitar string is plucked, the guitar string oscillates as a result of waves moving through the string. The vibrations of the string cause the air molecules to oscillate, forming sound waves. The frequency of the sound waves is equal to the frequency of the vibrating string. WebSep 7, 2024 · The existence of the periodic crystal lattice in solid materials provides a medium for characteristic vibrations. Between the lattice spacing, there are quantized vibrational modes called a phonon. \(^{[2]}\) The study of phonon is an important part of solid state physics, as they play an essential role in the physical properties of solids, the ...
