Label these images using three of the following terms: amplitude, wave length, frequency, sound source, crest, trough, resting point, sound wave, rarefaction,
compression, receptor, transverse, longitudinal (3 pts)

These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave.Feb 10, 2020
