![Diagram of a Longitudinal/compression wave and a transverse wave](http://static.sciencelearn.org.nz/images/images/000/004/097/full/PHYSICS_SOUND_ART_02_Longitudinal_Transverse_wave2_v3_9Sep19.jpg?1674173129)
Diagram illustrating longitudinal and transverse waves. The high points of the transverse waves (peaks) represent more-dense areas of the longitudinal waves, and the low points (troughs) represent less-dense areas. The arrows show the directions of wave material movement.
