Jakarta –
Transverse and longitudinal waves allow sound, light, water to reach humans. Even earthquake energy, radio waves, electromagnetic waves, and even waves that need a medium can have an impact on the surrounding environment.
Both waves actually both transmit energy from one place to another. Waves are also interpreted as vibrations that propagate. But transverse and longitudinal waves have fundamental differences.
Transverse Waves
Quoting the class 3A Physics book by Kamajaya, transverse waves have a movement perpendicular to the direction of vibration of the medium. One transverse wave consists of a trough and a crest.

Examples of transverse waves can be found in vibrations in a string moving up and down, movement on the surface of the water, and electromagnetism. Examples of electromagnetic waves are found in radio, microwave, infrared, and UV light.
Longitudinal Waves
The direction of the longitudinal wave coincides with the vibration of the medium, either in the same direction or in the opposite direction. Longitudinal waves are often said to be parallel to the direction of the medium and do not recognize peaks and valleys.

The particles of this wave move parallel to the direction of propagation of the wave. Which includes longitudinal waves such as sound waves, earthquake waves, or waves contained in mediums such as gases and liquids.
5 Differences between Transverse and Longitudinal Waves
1. Direction of Particle Movement
In a transverse wave, the particles of the medium move perpendicular to the direction of propagation of the wave. While in a longitudinal wave, the medium particles move parallel to the direction of propagation of the wave.
2. Wave Forms
Transverse waves can produce waves with a sinusoidal shape or waves that swing horizontally or vertically. Meanwhile, longitudinal waves can produce waves with compression and attenuation forms.
3. Transfer of Energy
In transverse waves, energy is transferred laterally through the medium. Meanwhile, in longitudinal waves, energy is transferred through the compression and attenuation of the particles of the medium.
4. Medium
Transverse waves can propagate in various mediums such as rope, water and vacuum. Meanwhile, longitudinal waves can propagate in mediums such as gases, liquids, and solids.
5. Detection
Transverse waves can be detected using devices such as electromagnetic field detectors, while longitudinal waves can be detected using a microphone or human earpiece.

It can be concluded that the differences between transverse and longitudinal waves can be seen through their direction, shape, energy transfer, medium, and how to detect them. Hopefully this article is useful.
