Examples of Longitudinal Waves in Everyday Life

KOMPAS.comLongitudinal wave is one of a kind wave based on the direction of vibration and propagation. Wave The longitudinal direction of vibration and the direction of propagation are parallel.

What is an example longitudinal wave in everyday life? Example of a longitudinal wave are sound waves, sonic explosions, ultrasonic waves, and also seismic waves.

Sound wave

The most common example of a longitudinal wave is a sound wave. Sound waves are described as having a spring-like shape with parallel directions of propagation and vibrations, typical of longitudinal waves.

All the sounds we hear are examples of longitudinal waves. For example, the sound of people talking, music, the sound of machines, the sound of echoes, the sound of thunder, the sound of animals and various other sounds heard in life.

sonic boom

Another example of a longitudinal wave is a sonic boom or better known as sonic boom. A sonic boom is a shock wave generated by a high-speed aircraft.

Reported from NASA, when an airplane is flying at or above the speed of sound, the air molecules can’t get out of the plane’s path quickly. This results in a compression wave that builds up and forms a large shock wave.

This shock wave is known as a sonic boom. These waves have parallel propagation and vibration directions, so they are classified as longitudinal waves.

Ultrasonic waves

Reported from Encyclopedia Britannica, ultrasonic waves are vibrations of frequencies above the range of human hearing, i.e. above 20 kilohertz.

Ultrasonic waves are basically sound waves. Thus, it has the form of a longitudinal wave whose direction of propagation and direction of vibration are parallel.

Seismic waves

Another example of electromagnetic waves is seismic waves. Reported from Michigan Technology University, seismic waves are waves produced by the movement of material in the earth.

Have you ever looked at a seismograph? A seismograph is a tool that records earthquake activity, especially during volcanic surveillance. Seismographs record seismic waves which are longitudinal waves.

Other examples of seismic waves besides earthquakes are vibrations that cause landslides, vibrations due to the movement of the earth’s plates, and also vibrations of volcanic eruptions.
