Such shear waves are then converted back to longitudinal waves at the solid / fluid surface propagating back through the fluid to the recording transducer enabling the measurement of shear wave velocities as well through a coupling medium.

After Heaviside's attempts to generalize Maxwell's equations, Heaviside came to the conclusion that electromagnetic waves were not to be found as longitudinal waves in " " free space " " or homogeneous media.

:: The analogy of a line of cars might work, but not as you stated it; it is sort of a complicated analogy since it is a longitudinal wave ( i . e . compression wave ).

These variations in tension set up longitudinal waves in the string which travel to the second can, causing its bottom to vibrate in a similar manner as the first can, thus recreating the sound heard by the second person.

:From looking at it, the article on sound isn't quite so helpful in explaining the propagation of the sound wave, but there's a bit of useful info in the article on longitudinal waves, of which sound is an example ( and the external links look pretty handy, too ).

We know that when a sound source is directed in a tube ( means it is kept at one end ) we get compressions and rarefractions . The longitudinal wave ( sound ) results from successive compressions ( state of maximum density and pressure ) and rarefactions ( state of minimum density and pressure ) of the medium . change in air density changes temperature of that part of air . my project is dealing with this fact . i want to alter the frequency of the incident sound wave and control the temperature . my project aims to assist machines which involve heat transfer by gases.
