Physics professor Clint Sprott of the University of Wisconsin shows one way to visualize these longitudinal pressure waves in his "Wonders of Physics" demonstration show. A loudspeaker is driven by a tone generator to produce single frequency sounds in a pipe which is filled with natural gas (methane).

Waves, where the parameter of interest (displacement, mechanical stress, etc.) oscillates along the axis of the wave propagation, are called longitudinal waves.

But sound waves are not transverse. Sound waves are longitudinal waves. If sound waves are moving south, the disturbance that they are creating is making the air molecules vibrate north-and-south (not east-and-west, or up-and-down.

A transverse wave is a moving wave that consists of oscillations occurring perpendicular to the direction of energy transfer. If a transverse wave is moving in the positive x -direction, its oscil...

Since electron plasma oscillations are assumed to cause nonthermal cosmical radiofrequency radiation, the problem of coupling between longitudinal and transversal plasma waves becomes important. Starting from the basic plasma equations all possible coupling mechanisms are deduced in a general way. ... Report Date : MAR 1961...

Concerning linearily coupled longitudinal and transversal rf waves, the difficulty of separation of the transversal part to get radiation out of the plasma, and the lack of a substantial source of radiation, because these waves are representing free plasma wave modes, are discussed. ...
