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.

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 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.
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 Simple Wave Simulator provides the learner an environment to explore the distinction between longitudinal and transverse waves, the wavelength-frequency-period relationship, sound waves as pressure waves, and much more.
Longitudinal waves are waves where the motion of the material in the wave is back and forth in the same direction that the wave moves. Sound waves (in air and in solids) are examples of longitudinal waves.
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.
