Transverse and Longitudinal Waves
10:43 PM |
In waves
propagating above the water surface, the water moves up and down as the
waves propagate, but the water particles generally do not move forward
along with the waves. Such waves are called
transverse waves, because they are perpendicular to the direction of
propagation, as shown in the figure below, the electro magnetic waves
belong to this type of wave, because the electric fields and magnetic
fields change periodically in perpendicular directions to each other. And also perpendicular to the direction of propagation.
In sound waves, the air alternately experiences sealing and stretching due to a shift in the direction of motion. Such waves are called longitudinal waves. The density is the area along longitudinal waves that have a higher pressure and density of the molecules than when no waves pass through the area. Meanwhile, regions with pressure and density of their molecules are lower than when no waves passing through are called strain.
Example of Longitudinal Waves In Slinki
All waves move energy not permanently but through the medium of propagation of the wave. A wave is also called a traveling wave or propagating wave due to the transfer of energy from one place to another due to vibration. In transverse waves, for example a rope wave, as shown below, shows waves propagating right along the rope. Each rope particle oscillates back and forth on the surface of the table.
The oscillating hand moves energy to the rope, which then carries it along the rope and is moved to the other end. The rope wave displacement graph can be observed in the following figure.

The following describes some of the terms that apply to transverse waves, based on the image above.
Wavelength, frequency, and wave velocity are the quantities applicable in longitudinal waves. The wavelength indicates the distance between successive darts or successive renggangan. Meanwhile, the frequency is the amount of pressure passing through a certain point per second. The speed at which each density appears to move states the wave velocity, which has a shape almost equal to the transverse velocity wave on the rope in the following equation:
For longitudinal wave propagation on solid rods, apply:
Where E is the material elastic modulus, and ρ is the density. Meanwhile, for propagation of longitudinal waves in liquids or gases are:
With B denoting Bulk Modulus.

The following describes some of the terms that apply to transverse waves, based on the image above.
- Peak waves, ie the highest points on the wave (eg point a and e).
- The bottom of the wave, ie the lowest points on the wave (eg dots c and g).
- Hill hill, ie o-a-b or d-e-f curvature.
- The wave valley, ie, b-c-d or f-g-h arches.
- Amplitude (A), ie maximum displacement (eg a'a and c'c).
- The wavelength (λ), ie the distance between two successive peaks (eg a-e) or the basis of two consecutive bases (c-g).
- Period (T) is the time required to travel a-e or c-g.
