A longitudinal wave is a type of wave that travels in the direction of the medium, but a transverse wave is another type of wave that travels in the direction of the medium. Longitudinal waves are made of compressions and rarefactions, while transverse waves are made of crests and troughs.

In obtaining the wave equation, we’ll need to get a handle on the pressure at the two ends of the given section of air, and then we’ll flgure out how these pressures cause the section to move.
The point where » = +A is typically called the \crest" of the wave and the point where » = ¡A is called the \trough" of the wave.2 The distance from crest to crest (or trough to trough) is called the \wavelength," the distance between points on the wave which have the same phase at the same instant of time.
24 Απρ 2022 · We now illustrate some examples of phase speed and group velocity by showing the displacement resulting from the superposition of two sine waves, as given by equation 1.38}, in the \(x\) -\(t \) plane. This is an example of a spacetime diagram, of which we will see many examples later on.
Longitudinal Waves. Longitudinal waves show areas of compressions and rarefactions; Diagram of a longitudinal wave. The compressions are areas of high pressure due to particles being close together. The rarefactions are areas of low pressure due to the particles spread further apart
Longitudinal waves - oscillation of particles is parallel to the direction of energy transfer. These are made up of compressions and rarefactions and can’t travel in a vacuum. Sound is an example of a longitudinal wave, and they can be demonstrated by pushing a slinky horizontally.
Sound waves (in air and in solids) are examples of longitudinal waves. When a tuning fork or stereo speaker vibrates it moves back and forth creating regions of compressed air (where the pressure is slightly higher) and regions in between where the air has a lower pressure (called a rarefaction).
