Examples of longitudinal waves include sound waves and seismic P-waves close P-waves Longitudinal seismic waves that are faster moving and travel through liquids and solids.

Understand how to identify amplitude and frequency of waves and features of transverse and longitudinal waves with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

Sound is propagated in the form of longitudinal waves. When sound travels from one medium to another, both its velocity and wavelength undergo changes.
