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.
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).
30 Αυγ 2024 · In longitudinal waves, the atoms of the medium move parallel to the direction that the energy is transported. The atoms have some sort of average spacing when they are in equilibrium. A force can act on them to cause them to move, pushing them closer together or pulling them apart than the equilibrium spacing.
v = f λ. 2.3.35 - Longitudinal waves. In longitudinal waves, the 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.
A longitudinal wave is a wave in which the particles of the medium are displaced in a direction parallel to the direction of energy transport. A longitudinal wave can be created in a slinky if the slinky is stretched out horizontally and the end coil is vibrated back-and-forth in a horizontal direction.
