Like transverse waves, longitudinal waves are mechanical waves, meaning they transfer energy through a medium. How else do longitudinal waves compare to transverse waves? What usually transmit longitudinal waves?
Longitudinal waves are a series of compressions and rarefactions, or expansions.
The amplitude is the difference in media density between the undisturbed density to the highest density in a compression. How do you measure the wavelength of a longitudinal wave?
